The computing environment for event reconstruction and analysis
at RHIC currently includes a farm of 200 Pentium-based
computers, several NFS and AFS servers, an HPSS storage system and 10TB of
RAID disk. The configuration of this environment is continuously
evolving to meet the expanding needs of the experiments as the RHIC
facility nears operation.
A system is being developed at BNL to monitor the performance of these
various subsystems, as well as to understand changes in the performance
due to configuration changes. An array of metrics is being developed
to provide measures of latencies, transfer rates and network
connectivity. This system will provide a running log of these metrics
and will allow correlations between metrics to be studied.
In order to determine the performance of specific tasks on these
distributed systems and provide platform independence, a
Java-based mobile-agent system is being used as the framework for task
distribution. Both the measurements and the code used to perform the
measurements are stored in a central database for scalability and
reproducibility. The design of the system and initial experiences in the
RHIC facility will be presented.
