I've been developing a test profile for the IOR file system benchmark utility. This test is commonly used to test a target file system from a number of other servers within a cluster. To do this IOR generally depends on the use of a helper application called mpirun (part of OpenMPI) in order to spinoff the required number of concurrent instances of IOR within the cluster.
For example: mpirun -n32 ./IOR -w -r -e -m -F -b 8g -t 1M -o ./test-file
Would spin off 32 concurrent instances of IOR
What I'd like to do is pass the parameter -n32 (or -n16 or -n1) to mpirun and other user defined switches to IOR.
Is there anything like this in other PTS tests that I could copy from or is this outside of the current functionality of PTS?
Thanks!
