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 <node list> [-n tasks-per-node] /path/simul -d /mnt/lustre/path/

Using prun is left as an exercise to the reader.
