SNUPI: A grid accounting and performance system employing portal services and RDBMS back-end
Victor Hazlewood, Ray Bean, Kenneth K. Yoshimoto · 2001
SNUPI, the System, Network, Usage and Performance Interface, provides an interface for resource utilization reporting for heterogeneous computer systems, including Linux clusters. SNUPI provides data collection tools, recommended RDBMS schema design, and Perl-DBI scripts suitable for portal services to deliver reports at the system, user, and job for heterogeneous systems across the enterprise, including Linux clusters. This paper will describe the background of process and project accounting systems for UNIX and Linux, process and batch accounting (JOBLOG) capabilities available for Linux, and describe the collection tools, the RDBMS schema and portal scripts that make up the Open Source SNUPI grid accounting and performance system as employed on the Linux cluster and other systems at NPACI/SDSC.
