Exploiting Thread-level parallelism (TLP) is a promising way to improve the performance of applications with the advent of general-purpose cost effective uni-processor and shared-memory multiprocessor systems. In this paper, we describe the OpenMP* implementation in the Intel(R) C++ and Fortran compilers for Intel platforms. We present our major design consideration and decisions in the Intel compiler for generating efficient multithreaded codes guided by OpenMP directives and pragmas. We describe several transformation phases in the compiler for the OpenMP* parallelization. In addition to compiler support, the OpenMP runtime library is a critical part of the Intel compiler. We present runtime techniques developed in the Intel OpenMP runtime library for exploiting thread-level parallelism as well as integrating the OpenMP support with other forms of threading termed as sibling parallelism. The performance results of a set of benchmarks show good speedups over the well-optimized serial code performance on Intel(R) Pentium- and Itanium-processor based systems.

One of the major challenges facing high performance computing is the daunting task of producing programs that will achieve acceptable levels of performance when run on parallel architectures. Although many organizations have been actively working in this area for some time, many programs have yet to be parallelized. Furthermore, some programs that were parallelized were done so for obsolete systems. These programs may run poorly, if at all, on the current generation of parallel computers. Therefore, a straightforward approach to parallelizing vectorizable codes is needed without introducing any changes to the algorithm or the convergence properties of the codes. Using the combination of loop-level parallelism, and RISC-based shared memory SMPs has proven to be a successful approach to solving this problem.

The objects that occur in scientific applications can be classified into spatial structures, e.g. meshes, grids, or graphs, and (numerical) data that are associated with these structures, e.g. grid functions and (sparse) matrices. Our C++ template library Janus rests on the observation that the spatial structures are conceptually more stable than the associated data. Janus provides a conceptual framework and generic components for mesh-based scientific applications. An outstanding feature of Janus is its unified treatment of regular and irregular structures. Our library has been developed using the paradigm of generic programming and is portably implemented on top of the Standard Template Library. It runs on top of MPI, but it can also be put onto other parallel platforms.

Clusters of shared-memory multiprocessors (SMPs) have become the most promising parallel computing platforms for scientific computing. However, SMP clusters significantly increase the complexity of user application development when using the low-level application programming interfaces MPI and OpenMP, forcing users to deal with both distributed-memory and shared-memory parallelization details. In this paper we present extensions of high Performance Fortran for SMP clusters which enable the compiler to adopt a hybrid parallelization strategy, efficiently combining distributed-memory with shared-memory parallelism. By means of a small set of new language features, the hierarchical structure of SMP clusters may be specified. This information is utilized by the compiler to derive inter-node data mappings for controlling distributed-memory parallelization across the nodes of a cluster, and intra-node data mappings for extracting shared-memory paxallelism. within nodes. Additional mechanisms are proposed for specifying inter- and intra-node data mappings explicitly, for controlling specific SM parallelization issues, and for integrating OpenMP routines in HPF applications. The proposed features are being realized within the ADAPTOR and VFC compiler. The parallelization strategy for clusters of SMPs adopted by these compilers is discussed as well as a hybrid-parallel execution model based on a combination of MPI and OpenMP. Early experimental results indicate the effectiveness of the proposed features.

We introduce the coordination language ALWAN and its programming environment which is characterised by properties such as high-level language abstraction, mixed language support, reuse of software, portability, and transparent multiprocessing. Furthermore, we outline the interfacing to C and Fortran. ALWAN has been implemented on several unix platforms as well as on machines such as: AP100, Cray T3D, Convex Exemplar, Intel Paragon, and IBM SP2.

The MILLIPEDE system is a small yet powerful interface of a virtual parallel machine (VPM) on top of distributed computing environments. MILLIPEDE is thus a convenient environment for porting various existing parallel programming languages, for the design of new parallel programming languages, and for the development of parallel applications. MILLIPEDE is fully implemented at the Technion on a cluster of PCs running Windows-NT. We briefly describe the MILLIPEDE interface and discuss the implementation issues of several parallel languages.
