Resource consumption profile and performance benchmark study of ARC classic and early prototype of ARC1
Observations from last few months reveal that Advanced Resource Connector (ARC) middleware becomes more and more popular among many research groups and we can observe the increasing tendency in number of CPUs connected to the Nordugrid infrastructure. Some of the reasons why this middleware is chosen are stability, reliability and modest administration needs of ARC middleware.
KnowARC project aims to develop a new generation of the ARC middleware, the "ARC1" which will offer standards-based interfaces and increased functionality. During the transition for the next generation ARC it is essential not to sacrifice the excellent performance capabilities of the current production middleware (ARC Classic).
In this report results from resource consumption profiling and performance benchmark study of the ARC Classic and the early prototype of ARC1 will be presented. In this stage the early prototype consists of the "container" for Web Services called Hosting Environment Daemon (HED) and of two Web Services - ECHO service and ARC Resource coupled EXecution service (A-REX). These components are complemented by the ECHO client for echo requests submission and the ARC prototype client used for submission of simple jsdl based jobs. From ARC Classic the grid manager, the gridftpd server and the information system modules were studied.
In resource consumption part we concentrate on CPU and memory consumption of the above mentioned components. In the performance benchmark part for ARC1 we present the numbers obtained for echo requests and job submission requests. In the performance benchmark part for ARC classic the numbers for job submission requests, data staging, data copy and local information query will be presented.
