PRIOmark

Info: PRIOmark is an easy portable I/O benchmark that measures file system and disk I/O performance of modern computer systems. It characterizes the file system performance of single and distributed systems by means of the POSIX I/O and MPI-IO file system interfaces.

Linux:

with MPICH

download "priomark_src-0.9.1.tar.gz" to your HPC computer or frontend
(Further information on howto download benchmarks with IPACS-Client in the second Client Guide section.)
$ tar -xvzf priomark_src-0.9.1.tar.gz
unpack the priomark-tar-file
$ cd priomark_0.9.1
$ vi Makefile
edit Makefile to set corret path to MPI: MPI_HOME = /opt/mpich/ch-p4
$ make
compile sourcecode
$ mpiexec -np 8 priomark > prio_16cpu_out
run PRIOmark benchmark with 8 nodes
(for PBS-Queues you have to write a script with a mpiexec-command, further informations in the third Client Guide section)
upload output file, e.g. "prio_16cpu_out" with the help of the IPACS-client
(Further information on how to upload results with the IPACS-Client in the fourth Client Guide section.)
during the upload the IPACS repository server will generate images to provide a graphical view of the results
