Simul Parallel File System Test Tool

simul
simul (available in the usual spot on the ftp site, or in ~morrone on MCR) tests most filesystem syscalls from one or more threads on one or more nodes. Building simul is straightforward.

It is easily run with either pdsh or prun. On MCR, this amounts to:

pdsh -E -w [-n tasks-per-node] /path/simul -d /mnt/lustre/path/

Using prun is left as an exercise to the reader.
