OpenMP compiler for distributed memory architectures

OpenMP compiler for a Software Distributed Shared Memory System SCASH

In this paper, we present an implementation of OpenMP compiler for a page-based software distributed shared memory system, SCASH on a cluster of PCs. For programming distributed memory multiprocessors such as clusters of PC/WS and MPP, message passing is usually used. A message passing system requires programmers to explicitly code the communication and makes writing parallel programs cumbersom...

OpenMP-oriented Applications for Distributed Shared Memory Architectures

The fast emergence of OpenMP as the preferable parallel programming paradigm for small-to-medium scale parallelism could decline unless OpenMP will show capabilities to be the model-of-choice for large scale high performance parallel computing of the next decade. The main stumbling block from adapting OpenMP for distributed shared memory (DSM) machines, which are based on architecture like cc-N...

Mpi+openmp Implementation of Memory-saving Parallel Pic Applications on Hierarchical Distributed-shared Memory Architectures

The combination of inter-node and intra-node domaindecomposition strategies for the development of memorysaving parallel Particle-in-cell simulation codes, targeted to hierarchical distributed-shared memory architectures, is discussed in this paper, along with its MPI+OpenMP implementation. Particular emphasis is given to the devised dynamic workload balancing technique.

Compiling for Distributed Memory Architectures

Distributed Memory Compiler Design for Sparse Problems

This paper addresses the issue of compiling concurrent loop nests in the presence of complicated array references and irregularly distributed arrays. Arrays accessed within loops may contain accesses that make it impossible to precisely determine the reference pattern at compile time. This paper proposes a run time support mechanism that is used e ectively by a compiler to generate e cient code...
