James, I wanted to mention IBT (informatics benchmarking toolkit) as a potential extensible informatics cluster benchmarking tool. http://bioteam.net/ibt/ Downside: o I haven't touched it in over a year, it could be further from usable than I think o It's currently configured as a single system benchmark tool not a cluster benchmark tool, although BioTeam could easily add another perl module it has available for execution over whatever DRM instead of local execution Upside: o Uses Autoconf as a mechanism for building one or more informatics applications from source on whatever UNIX system o Uses the perl Test::Harness framework for running one or more tests of the informatics tools that have been built o Records system environment, runtime metrics, MD5 checksum of input/ output/executables, and benchmark results in a Boulder::IO file o Parses collections of resulting Boulder::IO files and renders them into a brows-able SVG document Bill -- William Van Etten, PhD email: bill at bioteam.net mobile: 617-921-3358 iChat: williamvanettenphd at mac.com
