Texto completo da fonteThe ever-increasing supercomputer architectural complexity emphasizes the need for high-level parallel programming paradigms to design efficient, scalable and portable scientific applications. Among such paradigms, the task-based programming model abstracts away much of the architecture complexity by representing an application as a Directed Acyclic Graph (DAG) of tasks. Among them, the Sequential-Task-Flow (STF) model decouples the task submission step, sequential, from the parallel task execution step. While this model allows for further optimizations on the DAG of tasks at submission time, there is a key concern about the performance hindrance of sequential task submission when scaling. This thesis’ work focuses on studying the scalability of the STF-based StarPU runtime system (developed at Inria Bordeaux in the STORM team) for large scale 3D simulations of the CEA which uses dense linear algebra solvers. To that end, we collaborated with the HiePACS team of Inria Bordeaux on the Chameleon software, which is a collection of linear algebra solvers on top of task-based runtime systems, to produce an efficient and scalable dense linear algebra solver on top of StarPU up to 3,000 cores and 288 GPUs of CEA-DAM’s TERA-100 cluster

Texto completo da fonteThe increasing computational demands in SONAR processing chains lead to the choice of heterogeneous architectures based on GPGPU. The complexity of these architectures makes algorithm implementation challenging for individuals who are not specialists in both the application domain and parallel programming. This thesis aims to address this issue by leveraging task-based programming concepts. Static code analysis methods allowed us to group function calls on a GPU to limit certain overheads by increasing task granularity.To extend this approach to enable the utilization of multiple GPUs while controlling memory usage, we explored a moldable task model. This was instantiated into a new OpenMP directive that unifies several older parallelization directives. In this model, moldable tasks or sub-tasks retain the ability to have dependencies. The design of a prototype executive support for managing these moldable tasks focused on load balancing on a heterogeneous architecture and defining an algorithm to detect dependencies between such tasks. Experiments on a SONAR processing beamforming algorithm and the Cholesky factorization algorithm highlighted the method's benefits and some weaknesses in the implementation choices

Texto completo da fonteThis thesis makes several distinct contributions which rely on a dedicated task-based programming model. The novelty of this model resides in a dynamic adjustment of the quantity of embedded operations depending on the targeted processing unit. It is particularly well adapted to dynamically balance workloads between heterogeneous processing units. It better harnesses those units by strengthening responsiveness in the presence of execution times fluctuations induced by irregular codes or unpredictable hardware mechanisms. Moreover, the semantics and programming interface of the task-parallel model facilitates the use of automated behaviors such as data coherency of deported memories. It alleviates the burden of developers by taking care of this tedious work and which can be a source of errors. We developed H3LMS an execution platform designed to combine the propositions detailed in the thesis. The platform is integrated to the MPC programming environment in order to enhance cohabitation with other programming models and thus better harness clusters. H3LMS is elaborated to improve task scheduling between homogeneous and heterogeneous processing units by reducing the need to resort to distant accesses in a cluster node. This thesis also focuses on the adaptation of legacy codes which are originally designed to exploit traditional processors and may also consist of hundreds of thousand lines of code. The performance of this solution is evaluated on the Linpack library and on a legacy numerical application from the CEA

Texto completo da fonteSolving large sparse linear system is an essential part of numerical simulations. These resolve can takeup to 80% of the total of the simulation time.An efficient parallelization of sparse linear kernels leads to better performances. In distributed memory,parallelization of these kernels is often done by changing the numerical scheme. Contrariwise, in sharedmemory, a more efficient parallelism can be used. It’s necessary to use two levels of parallelism, a first onebetween nodes of a cluster and a second inside a node.When using iterative methods in shared memory, task-based programming enables the possibility tonaturally describe the parallelism by using as granularity one line of the matrix for one task. Unfortunately,this granularity is too fine and doesn’t allow to obtain good performance.In this thesis, we study the granularity problem of the task-based parallelization. We offer to increasegrain size of computational tasks by creating aggregates of tasks which will become tasks themself. Thenew coarser task graph is composed by the set of these aggregates and the new dependencies betweenaggregates. Then a task scheduler schedules this new graph to obtain better performance. We use as examplethe Incomplete LU factorization of a sparse matrix and we show some improvements made by this method.Then, we focus on NUMA architecture computer. When we use a memory bandwidth limited algorithm onthis architecture, it is interesting to reduce NUMA effects. We show how to take into account these effects ina task-based runtime in order to improve performance of a parallel program

Texto completo da fonteThe simulation has become an indispensable phase for conception of parallel processing systems, and enables to avoid construction of expensive prototypes. In this paper, a parallel process-oriented simulator written in OCCAM language has been developed. Our objective is to conceive a simulator adapted to a network of transputers for prototyping parallel processing systems by connecting directly the serial transputer channels. As a simulation example, a parallel processor system (coprocessor) based on hierarchical structure : master-slave has been realized at the processor-memory-switch level. The performance analysis is obtained via two queuing models : the former as independent M/M/1 systems and the latter as a M/M/s system. The experimental performance is measured respectively based on the independent tasks and the sequential tasks. The comparison of analytic and experimental results enables us to constate the advantage and limit of the coprocessor and to encourage us to its implementation

Texto completo da fonteToday, computers are implemented more frequently within systems in order to provide products with better functionalities and improved performance. The fast growing appeal on computing based systems forced industry to meet new short time to market and cost related challenges. Besides that, systems providers are facing rapidly growing needs to supply computers with reliability and safety requirements. This is because both applications and processors complexity keeps increasing and die size remains shrinking, thus making computers more vulnerable toward transient faults. For all these reasons, engineers try to find cost-efficient tools and flexible solutions to properly develop these systems. In this PhD thesis, we will study a redundancy based fault tolerance approach using OpenMP taskcentric programming model. In this approach, we enable OpenMP programmers to tag reliable tasks within a program to automatically replicate them and apply a triple modular redundancy. Voting mechanism is used to detect and recover from erroneous results and behavior. This technique allows developers to take advantage of recent and future multi and many-core based systems since the number of available and not fully exploited resources keeps increasing with the growing number of cores. In addition, we will implement within Nanos runtime system a task cancellation approach allowing us to free resources by cancelling erroneous unnecessary subtrees of tasks. It will also allow OpenMP programmers to easily code applications involving task cancellation and speculative execution. Moreover, we will study runtime enhancements to improve execution of OpenMP applications on NUMA based architectures

Texto completo da fonteThe most common method of Seismic Imaging is the RTM (Reverse Time Migration) which depends on wave propagation simulations in the subsurface. We focused on a 3D elastic wave propagator in anisotropic media, more precisely TTI (Tilted Transverse Isotropic). We directly worked in the Total code DIVA (Depth Imaging Velocity Analysis) which is based on a discretization by the Discontinuous Galerkin method and the Leap-Frog scheme, and developed for intensive parallel computing – HPC (High Performance Computing). We choose to especially target two contributions. Although they required very different skills, they share the same goal: to reduce the computational cost of the simulation. On one hand, classical boundary conditions like PML (Perfectly Matched Layers) are unstable in TTI media. We have proposed a formulation of a stable ABC (Absorbing Boundary Condition) in anisotropic media. The technique is based on slowness curve properties, giving to our approach an original side. On the other hand, the initial parallelism, which is based on a domain decomposition and communications by message passing through the MPI library, leads to load-imbalance and so poor parallel efficiency. We have fixed this issue by replacing the paradigm for parallelism by the use of task-based programming through runtime system. This PhD thesis have been done in the framework of the research action DIP (Depth Imaging Partnership) between the Total oil company and Inria
