With the advent of high-performance optimizing Java compilers, the open question is: How can Java programs best exploit massive parallelism? The authors have been contemplating this question via libraries of Java-routines for specifying and coordinating parallel codes. It would be most desirable to have these routines written in 100%-Pure Java; however, a more expedient solution is to provide Java wrappers (stubs) to existing parallel coordination libraries, such as MPI. MPI is an attractive alternative, as like Java, it is portable. We discuss both approaches here. In undertaking this study, we have also identified some minor modifications of the current language specification that would make 100%-Pure Java parallel programming more natural.","PeriodicalId":217385,"journal":{"name":"Proceedings.

In this context, it is argued that the definition of MPP should be extended to include LAN/WAN clusters or 'meta-computers'. The frontier for research for industry has moved on from mere parallel implementations of scientific simulations or commercial databases-rather, it is concerned with the problem of integrating computational and informational resources in a seamless and effective manner. Examples taken from recent research projects at the Parallel Applications Centre (PAC) are used to illustrate these points.","PeriodicalId":217385,"journal":{"name":"Proceedings.

MPI-2: standards beyond the message-passing model MPI-2:超越消息传递模型的标准

MPI-I confined itself to the well-known and understood message-passing model, in which a fixed number of processes with separate address spaces communicate only though cooperative operations such as send/receive or collective operations such as broadcast and reduce. In a second round of activity, the MPI Forum has recently concluded work on the MPI-2 Standard, which extends MPI beyond the message-passing programming model in a number of ways, including dynamic process management, one-sided operations, and some shared-memory operations. The message-passing model has also been used in MPI-2 as a model for parallel I/O. This paper describes the salient features of the MPI-2 Standard with special emphasis on the programming model that results from these extensions to the message-passing model.","PeriodicalId":217385,"journal":{"name":"Proceedings.

There is overwhelming demand for systems that support a universal format for computer programs and software components so users may benefit from their use on a wide variety of computing platforms. At present this demand is being met by commodity microprocessors together with standard operating system interfaces. However current systems do not offer a standard API (application program interface) for parallel programming, and the popular interfaces for parallel computing violate essential principles of modular or component-based software construction. Moreover microprocessor architecture is reaching the limit of what can be done usefully within the framework of superscalar and VLIW processor models. The next step is to put several processors (or the equivalent) on a single chip. This paper presents a set of principles for modular software construction and describes a program execution model based on functional programming that satisfies the set of principles. The implications of the principles for computer system architecture are discussed together with a sketch of the architecture of a multithread processing chip which promises to provide efficient execution of parallel computations while providing a sound base for modular software construction.","PeriodicalId":217385,"journal":{"name":"Proceedings.

We have developed Javelin, a Java-based prototype of a globally distributed heterogeneous, high-performance computational infrastructure that conveniently enables rapid execution of massively parallel applications. Our infrastructure consists of three entities: Hosts, clients, and brokers. Our goal is to allow users to buy and sell computational power using supply and demand, and market mechanisms to marshal computational power far beyond what can be achieved via conventional techniques. Several research issues must be worked out to make this vision a reality: allocating resources between computational objects via market mechanisms; expressing and enforcing scheduling and quality of service constraints; modeling programming in a global computing ecosystem; supporting heterogeneous execution without sacrificing computational speed; ensuring host security; global naming and communication; and client privacy.","PeriodicalId":217385,"journal":{"name":"Proceedings.

Work at Leeds has been studying the use of a typed shared memory system, based around the use of Shared Abstract Data Types (SADTs), to provide a structured view of sharing in a parallel machine. This has concentrated on the support for irregular problems, in which the patterns of communication and synchronisation can vary dynamically. SADTs augment the serial ADT with the ability to support concurrent access, encouraging modular and reusable code. The performance of an SADT can be optimised by supporting weak data consistency semantics (where this does not effect the correctness of the given application), and by careful tuning on the given parallel platform. The use of a well defined computational model is critical to the support of scalable and portable SADTs by capturing the dominant machine characteristics which effect performance. The Weakly coherent PRAM (WPRAM) model is an extension of the BSP approach, which has been used to design the SADTs, and to predict their performance. The paper provides a case study to illustrate this approach, based on the travelling salesman problem. Results for a 256 processor Cray T3D machine are provided, which demonstrate the high and scalable performance which has been achieved.","PeriodicalId":217385,"journal":{"name":"Proceedings.
