OpenMOSIX Benchmarking Notes:

This isn't completely figured out yet.

Modified Directions from: http://www.netlib.org/benchmark/hpl/software.html

Download and Installation

1. Download the tar-gzipped file, issue then "gunzip hpl.tgz; tar -xvf hpl.tar" and this should create an hpl directory containing the distribution. We call this directory the top level directory.

(www.netlib.org is 160.36.58.108)

1.a MAY NEED TO ADD LIBRARIES: MPI (message Passing Library), BLAS,

2. Create a file Make. in the top-level directory. For this purpose, you may want to re-use one contained in the setup directory. This Make. file essentially contains the compilers, libraries, and their paths to be used on your system.

3. Type "make arch=". This should create an executable in the bin/ directory called xhpl. For example, on our Linux PII cluster, I create a file called Make.Linux_PII in the top-level directory. Then, I type "make arch=Linux_PII". This creates the executable file bin/Linux_PII/xhpl.

make fails with

Make.inc: No such file or directory.

4. Quick check: run a few tests (assuming you have 4 nodes for interactive use) by issuing the following commands from the top level directory: "cd bin/ ; mpirun -np 4 xhpl". This should produce quite a bit of meaningful output on the screen.

5. Most of the performance parameters can be tuned, by modifying the input file bin//HPL.dat. See the tuning page or the TUNING file in the top-level directory.
