This is a step by step procedure on how to run the High Performance Linpack (HPL) benchmark on a Linux cluster using Intel-MPI. This was done on a Linux cluster of 128 nodes running Intel’s Nehalem processor 2.93 MHz with 12GB of RAM on each node. The operating system that was used is RedHat Enterprise Linux 5.3. The interconnectivity between the nodes was via Infiniband 4x-DDR using the standard RedHat EL 5.3 drivers.

You can also use my simple web tool to enter your system specs and it will suggest for you optimal input parameters for your HPL file before running the benchmark on the cluster. The tool can be accessed via the URL below under sourceforge:
