Message-Passing Performance of Various Computers
This report compares the performance of di erent computer systems for basic message passing. Latency and bandwidth are measured on Convex, Cray, Fujitsu, IBM, Intel, KSR, Meiko, nCUBE, NEC, SGI, and TMC multiprocessors. Communication performance is contrasted with the computational power of each system. The comparison includes both shared and distributed memory computers as well as networked wo...
متن کاملMessage-Passing Performance of Parallel Computers
In this paper we investigate some of the important factors which aaect the message-passing performance on parallel computers. Variations of low-level communication benchmarks that approximate realistic cases are tested and compared with the available Parkbench codes and benchmarking techniques. The results demonstrate a substantial divergence between message-passing performance measured by low-...
متن کاملImplementation of Production Systems on Message-Passing Computers
AbstructIn the past, researchers working on parallel implementations of production systems have focused on sharedmemory multiprocessors and special-purpose architectures. Message-passing computers have not been given as much attention. The main reasons for this have been the large messagepassing latency (as large as a few milliseconds) and high message-handling overheads (several hundred micros...
متن کاملSuitability of Message Passing Computers for Implementing Production Systems
Two important parallel architecture types are the shared-memory architectures and the message-passing architectures. In the past researchers working on the parallel implementations of production systems have focussed either on shared-memory multiprocessors or on special purpose architectures. Message-passing computers have not been studied. The main reasons have been the large messagepassing la...
متن کاملScaLAPACK: A Linear Algebra Library for Message-Passing Computers
This article outlines the content and performance of some of the ScaLAPACK software. ScaLAPACK is a collection of mathematical software for linear algebra computations on distributed-memory computers. The importance of developing standards for computational and message-passing interfaces is discussed. We present the di erent components and building blocks of ScaLAPACK and provide initial perfor...
