Abstract:
Validation is an important part of the development process of real-time systems. During validation, it should be proved that, the system meets its timing constraints. Therefore, worst-case execution time (WCET) analysis is performed. Currently, several WCET analysis tools are being developed. Researchers who develop new WCET analysis tools, need benchmarks to evaluate and compare their tools with alternatives. These benchmarks are called WCET benchmarks. In this paper a new WCET benchmark suite named ABench2020 is introduced. Its main focus is to provide benchmark programs in Ada programming language for WCET research. Therefore, ABench2020 includes several benchmark programs which were written in Ada programming language. The benchmark programs implement different program structures and properties to help researchers test their systems from different aspects. ABench2020 was published as open source. It is freely available over the Internet.

Abstract:
The rapid development of modern information technology has led to fierce competition in today's telecommunication industry. Telecommunication firms' accountability demands that operating efficiency be measured, maximized, and benchmarked. This study proposes an alternative context-dependent data envelopment analysis (DEA) technique to explore the managerial performance and the benchmarks of 24 global leading telecom operators. The analysis measures the relative attractiveness and progress of global telecom operators on a specific performance level against operators exhibiting poorer and/or better performance. The set operators are grouped into different levels of efficiency frontiers. Each efficiency frontier on a specific performance level is then used as an evaluation context for the relative attractiveness and progress. The performance of the efficient telecoms changes as the inefficient telecoms change their performance. It is shown that the context-dependent DEA can be used to differentiate and benchmark the performance of efficient DMUs. These benchmarks may give a first guideline for performance improvement of global telecommunication operators.

Abstract:
We investigate whether the positive associations between discretionary accrual proxies and beating earnings benchmarks hold for comparisons of groups segregated at other points in the distributions of earnings, earnings changes, and analystsbased unexpected earnings. We refer to these points as “pseudo” targets. Results suggest that the positive association between discretionary accruals and beating the profit benchmark extends to pseudo targets throughout the earnings distribution. We find similar results for the earnings change distribution. In contrast, we find few positive associations between discretionary accruals and beating pseudo targets derived from analysts-based unexpected earnings. We develop an additional analysis that accounts for the systematic association between discretionary accruals and earnings and earnings changes. Results suggest that the positive association between discretionary accruals and earnings intensifies around the actual profit benchmark (i.e., where earnings management incentives may be more pronounced). We find similar effects around the actual earnings increase benchmark. However, analogous patterns exist for cash flows around the profit and earnings increase benchmarks. In sum, we are unable to eliminate other plausible explanations for the associations between discretionary accruals and beating the profit and earnings increase benchmarks.

Abstract:
Abstract— Background subtraction is the dominant approach in the domain of moving object detection. Lots of research have been done to design or improve background subtraction models. However, there is a few well known and state of the art models which applied as a benchmark. Generally, these models are applied on different dataset benchmarks. Most of the time Choosing appropriate dataset is challenging due to the lack of datasets availability and the tedious process of creating the ground-truth frames for the sake of quantitative evaluation. Therefore, in this article we collected local video scenes for street and river taken by stationary camera focusing on dynamic background challenge. We presented a new technique for creating ground-truth frames using modelling, composing, tracking, and rendering each frame. Eventually we applied nine promising benchmark algorithms used in this domain on our local dataset. Results obtained by quantitative evaluations exposed the effectiveness of our new technique for generating the ground-truth scenes to be benchmarked with the original scenes using number of statistical metrics. Furthermore, results shows the outperformance of SuBSENSE model against other tested models.

Abstract:
Abstract Benchmarks are important to measure and aid in improve outcomes for surgical procedures. However, best achievable results that have been validated internationally for transsphenoidal surgery are not available. Therefore, we aimed to establish robust, standardized outcome benchmarks for transsphenoidal surgery of pituitary adenomas. A total of 2862 transsphenoidal tumor resections from 12 high-volume centers in 4 continents were analyzed. Patients were risk stratified and the median values of each center’s outcomes were established. The outcome benchmark was defined as the 75th percentile of all median values for a particular outcome as defined by Staiger et al. Out of 2862 patients, 1201 (41.9%) defined the benchmark cohort. The proportion of benchmark cases contributing to the final cohort ranged across centers between 22.1% to 59.7%. Within the benchmark cases, 928 (73.3%) patients underwent microscopic (MTS) and 263 (21.9%) patients endoscopic endonasal resection (EES). The overall postoperative complication rate was 18.9% with an in-hospital mortality between 0.0-0.8%. Benchmark cutoffs were ≤ 3.3% for reoperation rate, ≤ 4.6% for cerebrospinal fluid leak requiring intervention, and ≤ 15.3% for transient diabetes insipidus. At 6 months follow-up, benchmark cutoffs were calculated as follows: readmission rate: ≤ 7.1%, new hypopituitarism ≤ 15.5%, new neurological deficit ≤ 1.2%, tumor remnant ≤ 25.5%. This analysis defines benchmark values for transsphenoidal resection of pituitary adenomas targeting morbidity, mortality, surgical and tumor-related outcomes. The benchmark cutoffs can be used to assess different centers, patients’ populations, and novel surgical techniques.

Abstract:
Abstract Purpose Life cycle assessment (LCA) is considered a robust method to analyse the environmental impacts of products and is used in public and private market applications such as Green Public Procurement (GPP) and Environmental Management Systems (EMS). Despite the usefulness of the methodology, difficulties exist with the interpretation of LCA results. The use of benchmarks can facilitate this process, but there is yet little research on the definition of environmental benchmarks. The aim of this paper is to analyse the distribution of environmental performance used for the definition of the benchmark and how it effects the use in selected product categories. Method LCA results from 54 Environmental Product Declarations (EPDs) for insulation materials and 49 EPDs for bakery products are tested for their distribution. The outcome from the statistical analysis is used to compare and evaluate three calculation methods for a benchmark. Results and discussion The results of the study show that distributions and mid- and end-points of environmental performances of the studied indicators differ significantly for the two product categories. While some indicators for bakery products were closer to a normal distribution, most of the indicators are not normally distributed. This is reflected in the comparison of the chosen calculation methods for a benchmark, which showed that the distribution of the data affects the classification of the benchmark as well as the position of values on the benchmark. Conclusion The results emphasise that analysis of further product groups and the associated distribution of the environmental performance is needed to understand the implications of calculation methods on a benchmark. The availability of comparatively large datasets in a common structure is crucial for these analyses and can be facilitated through the digitalisation of LCA- and EPD-information. Furthermore, more research is needed on the communication formats for different benchmarking options, which must be applied for the different intended audiences to be effective.

Abstract:
In this work, we develop and test proxy-based diagnostic tools for comparing freshwater ecosystem services (FWES) risks across an international array of freshwater ecosystems. FWES threats are increasing rapidly under pressure from population, climate change, pollution, land use change, and other factors. We identified spatially explicit FWES threats estimates (referred to as threat benchmarks) and extracted watershed-specific values for an array of aquatic ecosystems in the Western Hemisphere (Ramsar sites). We compared these benchmark values to values extracted for sites associated with an international FWES threat investigation. The resulting benchmark threats appeared to provide a meaningful context for the diagnostic assessment of study site selection by revealing gaps in coverage of the underlying socio-environmental problem. In an effort to simplify the method, we tested regularly updated environmental and socioeconomic metrics as potential proxies for the benchmark threats using regression analysis. Three category proxies, aggregated from (i) external (global to regional, climate-related), (ii) internal (watershed management-related), and (iii) socioeconomic and governance related proxies produced strong relationships with water supply threat benchmarks, but only weak relationships with biodiversity-related and nutrient regulation benchmark threats. Our results demonstrate the utility of advancing global FWES status and threat benchmarks for organizing coordinated research efforts and prioritizing decisions with regard to international socio-environmental problems.

Abstract:
In recent years, many computer codes, based on Monte Carlo methods or deterministic calculations, have been developed to separately analyze different aspects regarding nuclear reactors. Nuclear reactors are very complex systems, which require an integrated analysis of all the variables which are intrinsically correlated: neutron fluxes, reaction rates, neutron moderation and absorption, thermal and power distributions, heat generation and transfer, criticality coefficients, fuel burnup, etc. For this reason, one of the main challenges in the analysis of nuclear reactors is the coupling of neutronics and thermal-hydraulics simulation codes, with the purpose of achieving a good modeling and comprehension of the mechanisms which rule the transient phases and the dynamic behavior of the reactor. This is very important to guarantee the control of the chain reaction, for a safe operation of the reactor. In developing simulation tools, benchmark analyses are needed to prove the reliability of the simulations. The experimental measurements conceived to be compared with the results coming out from the simulations are really precious and can provide useful information to improve the description of the physics phenomena in the simulation models. My PhD research activity was held in this framework, as part of the research project Analysis of Reactor COre (ARCO, promoted by INFN) whose task was the development of modern, flexible and integrated tools for the analysis of nuclear reactors, relying on the experimental data collected at the research reactor TRIGA Mark II, installed at the Applied Nuclear Energy Laboratory (LENA) at the University of Pavia. In this way, once the effectiveness and the reliability of these tools for modeling an experimental reactor have been demonstrated, these could be applied to develop new generation systems. In this thesis, I present the complete neutronic characterization of the TRIGA Mark II reactor, which was analyzed in different operating conditions through experimental measurements and the development of a Monte Carlo simulation tool (relied on the MCNP code) able to take into account the ever increasing complexity of the conditions to be simulated. First of all, after giving an overview of some theoretical concepts which are fundamental for the nuclear reactor analysis, a model that reconstructs the first working period of the TRIGA Mark II reactor, in which the “fresh” fuel was not heavily contaminated with fission reaction products, is described. In particular, all the geometries and the materials are described in the MCNP simulation model with good detail, in order to reconstruct the reactor criticality and all the effects on the neutron distributions. The very good results obtained from the simulations of the reactor at low power condition -in which the fuel elements can be considered to be in thermal equilibrium with the water around them- are then used to implement a model for simulating the full power condition (250kW), in which the effects arising from the temperature increase in the fuel-moderator must be taken into account. The MCNP simulation model was exploited to evaluate the reactor power distribution and a dedicated experimental campaign was performed to measure the water temperature within the reactor core. In this way, through a thermal-hydraulic calculation tool, it has been possible to determine the temperature distribution within the fuel elements and to include the description of the thermal effects in the MCNP simulation model. Thereafter, since the neutron flux is a crucial parameter affecting the reaction rates and thus the fuel burnup, its energy and space distributions are analyzed presenting the results of several neutron activation measurements. Particularly, the neutron flux was firstly measured in the reactor's irradiation facilities through the neutron activation of many different isotopes. Hence, in order to analyze the energy flux spectra, I implemented an analysis tool, based on Bayesian statistics, which allows to combine the experimental data from the different activated isotopes and reconstruct a multi-group flux spectrum. Subsequently, the spatial neutron flux distribution within the core was measured by activating several aluminum-cobalt samples in different core positions, thus allowing the determination of the integral and fast flux distributions from the analysis of cobalt and aluminum, respectively. Finally, I present the results of the fuel burnup calculations, that were performed for simulating the current core configuration after a 48 years-long operation. The good accuracy that was reached in the simulation of the neutron fluxes, as confirmed by the experimental measurements, has allowed to evaluate the burnup of each fuel element from the knowledge of the operating hours and the different positions occupied in the core over the years. In this way, it has been possible to exploit the MCNP simulation model to determine a new optimized core configuration which could ensure, at the same time, a higher reactivity and the use of less fuel elements. This configuration was realized in September 2013 and the experimental results confirm the high quality of the work done. The results of this Ph.D. thesis highlight that it is possible to implement analysis tools -ranging from Monte Carlo simulations to the fuel burnup time evolution software, from neutron activation measurements to the Bayesian statistical analysis of flux spectra, and from temperature measurements to thermal-hydraulic models-, which can be appropriately exploited to describe and comprehend the complex mechanisms ruling the operation of a nuclear reactor. Particularly, it was demonstrated the effectiveness and the reliability of these tools in the case of an experimental reactor, where it was possible to collect many precious data to perform benchmark analyses. Therefore, for as these tools have been developed and implemented, they can be used to analyze other reactors and, possibly, to project and develop new generation systems, which will allow to decrease the production of high-level nuclear waste and to exploit the nuclear fuel with improved efficiency.

Abstract:
An important objective in statistical risk assessment is estimation of minimum exposure levels, called Benchmark Doses (BMDs) that induce a pre-specified Benchmark Response (BMR) in a target population. Established inferential approaches for BMD analysis typically involve one-sided, frequentist confidence limits, leading in practice to what are called Benchmark Dose Lower Limits (BMDLs). Appeal to hierarchical Bayesian modeling and credible limits for building BMDLs is far less developed, however. Indeed, for the few existing forms of Bayesian BMDs, informative prior information is seldom incorporated. Here, a new method is developed by using reparameterized quantal-response models that explicitly describe the BMD as a target parameter. This potentially improves the BMD/BMDL estimation by combining elicited prior belief with the observed data in the Bayesian hierarchy. Besides this, the large variety of candidate quantal-response models available for applying these methods, however, lead to questions of model adequacy and uncertainty. Facing this issue, the Bayesian estimation technique here is further enhanced by applying Bayesian model averaging to produce point estimates and (lower) credible bounds. Implementation is facilitated via a Monte Carlo-based adaptive Metropolis (AM) algorithm to approximate the posterior distribution. Performance of the method is evaluated via a simulation study. An example from carcinogenicity testing illustrates the calculations.

Abstract:
An important objective in statistical risk assessment is estimation of minimum exposure levels, called Benchmark Doses (BMDs), that induce a pre-specified Benchmark Response (BMR) in a target population. Established inferential approaches for BMD analysis typically involve one-sided, frequentist confidence limits, leading in practice to what are called Benchmark Dose Lower Limits (BMDLs). With this context, a quantitative methodology is developed to characterize vulnerability among 132 U.S. urban centers ('cities') to terrorist events, applying a place-based vulnerability index to a database of terrorist incidents and related human casualties. A centered autologistic regression model is employed to relate urban vulnerability to terrorist outcomes and also to adjust for autocorrelation in the geospatial data. Risk- analytic BMDs are then estimated from this modeling framework, wherein levels of high and low urban vulnerability to terrorism are identified. This new, translational adaptation of the risk-benchmark approach, including its ability to account for geospatial autocorrelation, is seen to operate quite flexibly in this socio-geographic setting. Further, alternative definitions for neighborhoods are considered to extend the autologistic benchmark paradigm to non-spatial settings. All 3108 counties in the contiguous 48 U.S. states are studied to identify a benchmark dose variable as the number of hazards. This is employed to benchmark billion-dollar losses across each county. County-level resilience is used as a potential characteristic for defining the neighborhood structure within the autologistic model.

Abstract:
The assessment of the performance of learners by means of benchmark experiments is established exercise. In practice, benchmark studies are a tool to compare the performance of several competing algorithms for a certain learning problem. Cross-validation or resampling techniques are commonly used to derive point estimates of the performances which are compared to identify algorithms with good properties. For several benchmarking problems, test procedures taking the variability of those point estimates into account have been suggested. Most of the recently proposed inference procedures are based on special variance estimators for the cross-validated performance. We introduce a theoretical framework for inference problems in benchmark experiments and show that standard statistical test procedures can be used to test for differences in the performances. The theory is based on well defined distributions of performance measures which can be compared with established tests. To demonstrate the usefulness in practice, the theoretical results are applied to benchmark studies in a supervised learning situation based on artificial and real-world data.

Abstract:
During the past ten years, considerable research has been conducted with the aim of developing, implementing and verifying "advanced analysis" techniques suitable for the non-linear analysis and design of steel framed structures. With the use of one of these methods, the simplified concentrated methods, comprehensive assessment of the actual failure modes and ultimate strengths of framing systems is now possible in practical design situations, without resort to conventional elastic methods of analysis and semiempirical specification equations. This research has the potential to extend the creativity of the structural engineer and simplify the design process, while ensuring greater economy and more uniform safety in certain design situations. However, the application of concentrated plasticity methods is currently restricted to two dimensional steel frame structures that are fully laterally restrained and constructed from compact sections (i.e. sections not subject to local and/or lateral buckling effects). Unfortunately this precludes the use of advanced analysis from the design of frames consisting of cold-formed sections and a significant proportion of hot-rolled universal beam sections. Therefore research is currently under way to develop concentrated plasticity methods of analysis for steel frame structures subject to local and/or lateral buckling effects. This thesis was aimed at developing appropriate benchmark solutions that are needed to validate these simplified methods of analysis. Finite element analyses and five large scale experiments were conducted in order to study the ultimate strength behaviour of two-dimensional single bay single storey steel frames subjected to local and/or lateral buckling effects. The frames comprised of cold-formed rectangular hollow sections and hot-rolled I-sections. A good agreement between the results from finite element analyses and experiments validated the accuracy of the finite element model used. The finite element model was then used to develop benchmark solutions for two-dimensional single storey, single bay steel frames comprising cold-formed rectangular hollow sections and hot-rolled I-sections subjected to local and/or lateral buckling effects. This thesis presents the details of finite element analyses and large scale experiments and their results, and a series of analytical benchmark solutions that can be used for the verification of simplified concentrated plasticity methods of analysis.

Abstract:
Scania OmniExpress Busproduction Finland Oy in Lahti, a company that manufactures buses of product family Scania Interlink LD, Scania Interlink MD, Scania Interlink HD and Scania Citywide LE Suburban. As Scania receives larger customer orders, these orders are divided into both Scania Production Słupsk S.A. and Scania OmniExpress Busproduction Finland Oy, which bring a desire to harmonize these factories. To achieve this harmonization an investigation is required of Scania OmniExpress Busproduction Finland Oy analysis process and comparison with Scania Production Słupsk S.A. To keep up the permanent development outcome, Strategic Plan Scania Production Lahti requires a survey of the painting process in Lahti, Finland. Based on this, an internal cost performance benchmark has been implemented between the factories. Through a currant status analysis of both facility’s, based on Strategic Plan Scania Production Lahti methods and strategies, as well as complementing this with external methods and theory, the gap between the factories has been conducted from a cost perspective. Based on the more in-depth analysis made in Scania OmniExpress Busproduction Finland Oy, an improvement work has been carried out.
Scania OmniExpress Busproduction Finland Oy i Lahti, tillverkar idag bussfamiljerna Scania Interlink LD, Scania Interlink MD, Scania Interlink HD och Scania Citywide LE Suburban. För att kunna leverera vid större kundordrar delas dessa upp mellan två Scaniaägda fabriker, Scania Production Słupsk S.A. och Scania OmniExpress Busproduction Finland Oy, detta medför att en harmonisering krävs mellan fabrikerna så att slutprodukten blir identisk. För att uppnå denna harmonisering utfördes denna studie mellan dessa fabriker. Att jobba med ständiga förbättringar är djupt inprintat i Scanias visioner och mål. I arbetet med ständiga förbättringar för processer skulle målerprocessen förbättras i denna studie. Genom en nulägesanalys i båda fabrikerna baserad på Strategic Plan Scania Production Lahti metoder och strategier såväl som kompliment från externa metoder och teorier har prestanda gapet identifierats. Baserat på en såväl djupare nulägesanalys i Scania OmniExpress Busproduction Finland Oy, har ett förbättringsarbete utförts.

Abstract:
AbstractWe consider turn-based stochastic 2-player games on graphs with $$\omega $$ ω -regular winning conditions. We provide a direct symbolic algorithm for solving such games when the winning condition is formulated as a Rabin condition. For a stochastic Rabin game with k pairs over a game graph with n vertices, our algorithm runs in $$O(n^{k+2}k!)$$ O ( n k + 2 k ! ) symbolic steps, which improves the state of the art.We have implemented our symbolic algorithm, along with performance optimizations including parallellization and acceleration, in a BDD-based synthesis tool called . We demonstrate the superiority of compared to the state of the art on a set of synthetic benchmarks derived from the VLTS benchmark suite and on a control system benchmark from the literature. In our experiments, performed significantly faster with up to two orders of magnitude improvement in computation time.

Abstract:
AbstractWe present a detailed study of roundoff errors in probabilistic floating-point computations. We derive closed-form expressions for the distribution of roundoff errors associated with a random variable, and we prove that roundoff errors are generally close to being uncorrelated with their generating distribution. Based on these theoretical advances, we propose a model of IEEE floating-point arithmetic for numerical expressions with probabilistic inputs and an algorithm for evaluating this model. Our algorithm provides rigorous bounds to the output and error distributions of arithmetic expressions over random variables, evaluated in the presence of roundoff errors. It keeps track of complex dependencies between random variables using an SMT solver, and is capable of providing sound but tight probabilistic bounds to roundoff errors using symbolic affine arithmetic. We implemented the algorithm in the PAF tool, and evaluated it on FPBench, a standard benchmark suite for the analysis of roundoff errors. Our evaluation shows that PAF computes tighter bounds than current state-of-the-art on almost all benchmarks.

Abstract:
Finite element weld residual stress modelling procedures involve complex non-linear analyses where many assumptions and approximations have to be made by the analyst. Weld modelling guidelines for inclusion in the R6 defect assessment procedure are in preparation and will be accompanied by a series of validation benchmarks that can be used to evaluate the accuracy of weld modelling procedures and assess their suitability for use in fracture assessments. It is intended to base one of the benchmarks on a stainless steel bead-on-plate weldment that has been extensively studied by members of Task Group 1 of the NeT European Network project. This paper uses round robin residual stress measurements from the NeT project to derive a statistically based ‘best estimate’ distribution of transverse stress passing through the wall-section at mid-length of the bead-on-plate weldment. The accuracy of a state-of-the-art residual stress prediction is benchmarked against the best estimate measurements using a root mean square error analysis and comparisons of decomposed components of stress. The appropriateness of using the predicted residual stresses in fracture assessments is assessed by comparing stress intensity factors based on the measured and predicted distributions of stress. The results from these studies will be used to help establish accuracy targets and acceptance criteria for the welding benchmark.

Abstract:
Finite element methods are used increasingly to predict weld residual stresses. This is a relatively complex use of the finite element method, and it is important that its practitioners are able to demonstrate their ability to produce accurate predictions. Extensively characterised benchmark problems are a vital tool in achieving this. However, existing benchmarks are relatively complex and not suitable for analysis by novice weld modellers. This paper describes two benchmarks based upon a simple beam specimen with a single autogenous weld bead laid along its top edge. This geometry may be analysed using either 3D or 2D FE models and employing either block-dumped or moving heat source techniques. The first, simpler, benchmark is manufactured from AISI 316 steel, which does not undergo solid state phase transformation, while the second, more complex, benchmark is manufactured from SA508 Cl 3 steel, which undergoes solid state phase transformation during welding. A number of such beams were manufactured using an automated TIG process, and instrumented with thermocouples and strain gauges to record the transient temperature and strain response during welding. The resulting residual stresses were measured using diverse techniques, and showed markedly different distributions in the austenitic and ferritic beams. The paper presents the information necessary to perform and validate finite element weld residual stress simulations in both the simple austenitic beam and the more complex ferritic beam, and provides performance measures for the austenitic beam problem.

Abstract:
Abstract In the paper at first the theoretical basis for the simulation of piezothermoelastic smart structures is discussed briefly. Then an overview about our finite element simulation tool for smart structures is given. During the development of this analysis tool several test examples have been solved and compared with theoretical results from the literature as well as experimental results. During this process of software verification and qualification we were tackled with several problems, such as incomplete and incorrect data from literature, especially missing material data, incorrect boundary and load conditions, etc. Consequently, a collection of well documented benchmark examples should be created for smart structures. The selection of suited examples should follow the guidelines of the well established NAFEMS benchmarks in other fields of mechanics. In the paper a first collection of some smart structures benchmark problems is proposed and discussed.

Abstract:
This deliverable focuses on the proling activities developed in the project with the partner's applications. To perform this proling activities, a couple of benchmarks were dened in collaboration with WP5. The rst benchmark is an embarrassingly parallel benchmark that performs a read and then multiple writes of the same object, with the objective of stressing the memory and storage systems and evaluate the overhead when these reads and writes are performed in parallel. A second benchmark is dened based on the Continuation Multi Level Monte Carlo (C-MLMC) algorithm. While this algorithm is normally executed using multiple levels, for the proling and performance analysis objectives, the execution of a single level was enough since the forthcoming levels have similar performance characteristics. Additionally, while the simulation tasks can be executed as parallel (multi-threaded tasks), in the benchmark, single threaded tasks were executed to increase the number of simulations to be scheduled and stress the scheduling engines. A set of experiments based on these two benchmarks have been executed in the MareNostrum 4 supercomputer and using PyCOMPSs as underlying programming model and dynamic scheduler of the tasks involved in the executions. While the rst benchmark was executed several times in a single iteration, the second benchmark was executed in an iterative manner, with cycles of 1) Execution and trace generation; 2) Performance analysis; 3) Improvements. This had enabled to perform several improvements in the benchmark and in the scheduler of PyCOMPSs. The initial iterations focused on the C-MLMC structure itself, performing re-factors of the code to remove ne grain and sequential tasks and merging them in larger granularity tasks. The next iterations focused on improving the PyCOMPSs scheduler, removing existent bottlenecks and increasing its performance by making the scheduler a multithreaded engine. While the results can still be improved, we are satised with the results since the granularity of the simulations run in this evaluation step are much ner than the one that will be used for the real scenarios. The deliverable nishes with some recommendations that should be followed along the project in order to obtain good performance in the execution of the project codes.

Abstract:
This review synthesises evidence on water in sustainable agriculture standards. Sustainable agricultural standards, hereafter standards, is a broad term encompassing certification schemes, tools, and programmes. The International Trade Centre’s Sustainability Standards Map includes 166 agricultural standards . However, there is a smaller number of prominent standards that are popularly used by major retailers or for particular commodities. Two studies looking at how water is considered in standards selected smaller numbers: Morgan (2017) benchmarks 25 popular use conventional agricultural standards and organic standards, whilst Vos & Boelens (2014) selected eight prominent standards for their analysis. The evidence base for this request was limited. Whilst water is included in individual standards, there is limited research on the efficacy or impact of standards on water issues. This review identified an extremely small number of studies that either assessed or benchmarked standards’ water related requirements or the impacts of certification and water requirements on water resources.
