Application Performance of a Linux Cluster Using Converse
نویسندگان
چکیده
Clusters of PCs are an attractive platform for parallel applications because of their cost effectiveness. We have implemented an interoperable runtime system called Converse on a cluster of Linux PCs connected by an inexpensive switched Fast Ethernet. This paper presents our implementation and its performance evaluation. We consider the question of the performance impact of using inexpensive communication hardware on real applications, using a large production-quality molecular dynamics program, NAMD, that runs on this cluster.

متن کاملOptimizing Performance on Linux Clusters Using Advanced Communication Protocols: How 10+ Teraflops Was Achieved on a 8.6 Teraflops Linpack-Rated Linux Cluster
Advancements in high-performance networks (Quadrics, Infiniband or Myrinet) continue to improve the efficiency of modern clusters. However, the average application efficiency is as small fraction of the peak as the system’s efficiency. This paper describes techniques for optimizing application performance on Linux clusters using Remote Memory Access communication protocols. The effectiveness of...
متن کاملOptimizing System Services in Virtualized Machines for Improved Execution of Parallel Applications
Hardware virtualization in the x86 architecture has enabled the use of virtual machine monitors in Beowulf clusters. In turn, each application user can then run a virtual guest operating system of his/her choice. Of course virtualizing and sharing the hardware resources in a Beowulf cluster will add additional overheads that may negatively effect performance of the application. However, the use...
متن کاملParallel Processing with Autonomous Databases in a Cluster System
We consider the use of a cluster system for Application Service Provider (ASP). In the ASP context, hosted applications and databases can be update-intensive and must remain autonomous. In this paper, we propose a new solution for parallel processing with autonomous databases, using a replicated database organization. The main idea is to allow the system administrator to control the tradeoff be...

A collection of performance benchmarks have been run on an IBM System X iDataPlex cluster using two different operating systems. Windows HPC Server 2008 (WinHPC) and Red Hat Enterprise Linux v5.4 (RHEL5) are compared using SPEC MPI2007 v1.1, the High Performance Computing Challenge (HPCC) and National Science Foundation (NSF) acceptance test benchmark suites. Overall, we find the performance of...
