Important Notes

• All tests are archived in the src directory.
• The bps suite is best run as a normal user, not root. Some of the tests (i.e. NAS parallel) will not run as root.
• Not all features of the command line interface are possible with the GUI.
• When using Netpipe and Netperf Benchmarks, rsh with no password must be permitted between the nodes.
• Under normal operation, xbps will always preserve the existing log directory. This feature is to ensure previous results will not be overwritten. You can copy previous log files (from log directories) into the current log directory for bps-html conversion.
• Also, the tests have been designed so that the BPS rpm only needs to be installed on the master node. For this to work, the BPS log directory must be mounted on all nodes (e.g. under /home).
• NAS Parallel Benchmarks have been tested with Paralogic's versions of LAM and MPICH. Please see the NAS documentation for more information. Rather than limit potential BPS users, these are not made a part of the required packages list. The benchmark scripts have been written to rely on the three environment variables (LAM_HOME for LAM-MPI, MPICH_HOME for MPICH, and MPIPRO_HOME for MPI-PRO, and MPICH). If you are having problems with the NAS benchmarks, extract the npb.tar.gz archive in the/usr/bps/src directory and try running the scripts manually (see below). Consult the README.plogic file for more information. Also, if you wish to use the Portland Group or the Intel Compilers make sure they are properly configured. Note: on Paralogic clusters, these tests are designed to use modules for easy transition from one MPI/Compiler version to another.
