Shared Memory Architecture for Simulating Sediment-Fluid Flow by OpenMP

A Shared Memory Benchmark in OpenMP

The efficient use of the memory system is a key issue for the performance of many applications. A benchmark written with OpenMP is presented that measures several aspects of a shared memory system like bandwidth, memory latency and inter-thread latency. Special focus is on revealing and identifying bottlenecks and possible hierarchies in the main memory system.

Automatic Scaling of OpenMP Beyond Shared Memory

OpenMP is an explicit parallel programming model that offers reasonable productivity. Its memory model assumes a shared address space, and hence the direct translation as done by common OpenMP compilers requires an underlying shared-memory architecture. Many lab machines include 10s of processors, built from commodity components and thus include distributed address spaces. Despite many efforts ...

Workload decomposition strategies for shared memory parallel systems with OpenMP

A crucial issue in parallel programming (both for distributed and shared memory architectures) is work decomposition. Work decomposition task can be accomplished without large programming effort with use of high-level parallel programming languages, such as OpenMP. Anyway particular care must still be payed on achieving performance goals. In this paper we introduce and compare two decomposition...

46 1070-9924/98/$10.00 © 1998 IEEE IEEE COMPUTATIONAL SCIENCE & ENGINEERING Application developers have long recognized that scalable hardware and software are necessary for parallel scalability in application performance. Both have existed for some time in their lowest common denominator form, and scalable hardware—as physically distributed memories connected through a scalable interconnection...
