Abstract (sommario):

Remote procedure call (RPC) and shared variable are communication abstractions which allow the various processes of a distributed program, often modelled as clients and servers, to communicate with one another across machine boundaries. A key requirement of the abstractions is to mask the machine and communication failures that may occur during the client-server communications. In practice, many distributed applications can inherently tolerate failures under certain situations. If such application layer information is available to the client-server communication layer (RPC and shared variable), the failure masking algorithms in the communication layer may relax the constraints under which the algorithms may have to operate if the information is not available. The relaxation significantly simplifies the algorithms and the underlying message transport layer and allows formulation of efficient algorithms. This application-driven approach forms the backbone of the failure masking techniques described in the thesis, as outlined below: Orphan handling in RPCs: Using the application-driven approach, the thesis introduces a new technique of adopting the orphans caused by failures during RPCs. The adoption technique is preferable to orphan killing because orphan killing wastes any work already completed and requires rollback which may be expensive and sometimes not meaningful. The thesis incorporates orphan adoption into two schemes of replicating a server: i) Primary-secondary scheme in which one of the replicas of the server acts as the primary and executes RPCs from clients while the other replicas stand by as secondaries. When the primary fails, one of the secondaries becomes the primary, restarts the server execution from the most recent checkpoint and adopts the orphan, ii) Replicated execution scheme in which an RPC on the server is executed by more than one replica of the server. When any of the replicas fails, the orphan generated by the failure is adopted by the surviving replicas. Both schemes employ call re-executions by servers based on the application-level idempotency properties of the calls. Access to shared variables: Contemporary distributed programs deal with a new class of shared variables such as information on name bindings, distributed load and leadership within a service group. Since the consistency constraints on such system variables need not be as strong as those for user data, the access operations on the variables may be made simpler using this application layer information. Along this direction, the thesis introduces an abstraction, which we call application-driven shared variable, to govern access operations on the variables. The algorithms for the access operations on a variable use intra-server group communication and enforce consistency of the variable to the extent required by the application. The thesis describes complete communication models incorporating the application-driven approach to mask failures.

Abstract (sommario):

This thesis shows that both data and code must be efficiently distributed to achieve good performance in a distributed system. Most previous research has either tried to distribute code structures to improve parallelism or to distribute data to reduce communication costs. Code distribution (exploiting functional parallelism) is an effort to distribute or to duplicate function codes to optimize parallel performance. On the other hand, data distribution tries to place data structures as close as possible to the function codes that use it, so that communication cost can be reduced. In particular, dataflow researchers have primarily focused on code partitioning and assignment. We have adapted existing data allocation algorithms for use with an existing dataflow-based system, ParPlum. ParPlum allows the execution of dataflow graphs on networks of workstations. To evaluate the impact of data allocation, we extended ParPlum to more effectively handle data structures. We then implemented tools to extract from dataflow graphs information that is relevant to the mapping algorithms and fed this information to our version of a data distribution algorithm. To see the relation between code and data parallelism we added optimization to optimize the distribution of the loop function components and the data structure access components. All of these are done automatically without programmer or user involvement. We ran a number of experiments using matrix multiplication as our workload. We used different numbers of processors and different existing partitioning and allocation algorithm. Our results show that automatic data distribution greatly improves the performance of distributed dataflow applications. For example, with 15 x 15 matrices, applying data distribution speeds up execution about 80% on 7 machines. Using data distribution and our code-optimizations on 7 machines speeds up execution over the base case by 800%. Our work shows that it is possible to make efficient use of distributed networks with compiler support and shows that both code mapping and data mapping must be considered to achieve optimal performance.

Abstract (sommario):

This work describes the design and implementation details of a reliable group communication mechanism. The mechanism guarantees that messages will be received by all the operational members of the group or by none of them (atomicity). In addition, the sequence of messages will be the same at each of the recipients (order). The message ordering property can be used to simplify distributed database systems and distributed processing algorithms. The proposed mechanism continues to operate despite process, host and communication link failures (survivability). Survivability is essential in fault-tolerant applications.

Abstract (sommario):

Parallel computing can take many forms. From a user's perspective, it is important to consider the advantages and disadvantages of each methodology. The following project attempts to provide some perspective on the methods of parallel computing and indicate where the tradeoffs lie along the continuum. Problems that are parallelizable enable researchers to maximize the computing resources available for a problem, and thus push the limits of the problems that can be solved. Solving any particular problem in parallel will require some very important design decisions to be made. These decisions may dramatically affect portability, performance, and cost of implementing a software solution to the problem. The results gained from this work indicate that although performance improvements are indeed possible---they are heavily dependent on the application in question and may require much more programming effort and expertise to implement.

Abstract (sommario):

This thesis concentrates on the derivation of a modularised version of the DMOS distributed garbage collection algorithm and the implementation of this algorithm in a distributed computational environment. DMOS appears to exhibit a unique combination of attractive characteristics for a distributed garbage collector but the original algorithm is known to contain a bug and, previous to this work, lacks a satisfactory, understandable implementation. The relationship between distributed termination detection algorithms and distributed garbage collectors is central to this thesis. A modularised DMOS algorithm is developed using a previously published distributed garbage collector derivation methodology that centres on mapping centralised collection schemes to distributed termination detection algorithms. In examining the utility and suitability of the derivation methodology, a family of six distributed collectors is developed and an extension to the methodology is presented. The research work described in this thesis incorporates the definition and implementation of a distributed computational environment based on the ProcessBase language and a generic definition of a previously unimplemented distributed termination detection algorithm called Task Balancing. The role of distributed termination detection in the DMOS collection mechanisms is defined through a process of step-wise refinement. The implementation of the collector is achieved in two stages; the first stage defines the implementation of two distributed termination mappings with the Task Balancing algorithm; the second stage defines the DMOS collection mechanisms.

Abstract (sommario):

In recent years, the field of distributed processing, distributed systems, has undergone great change, and has been an area attracting tremendous research and development efforts. This thesis explores the various current methodologies for designing, developing and implementing distributed systems using the Ada programming language, and goes on to implement a simulation of a distributed store system using the "virtual node" design approach. After a brief introduction on distributed systems in general, an investigation of the basic issues and problems involved in distributing Ada programs coupled with an analysis and comparison of various approaches to developing distributed Ada systems is carried out. It is shown that one of the critical problems of Ada in a distributed environment is its implicit assumption of a single memory processor. A simulation of a distributed system (store system) is carried out using the virtual node method of developing distributed Ada systems. The various stages of this design method including interface task specification are stepped through. A sample run of the. system is given, including the customer file, stock file data and the monitored output of the system.
