Hi All,

We've recently had an issue where a job on our client GPFS cluster caused out main storage to go extremely slowly.   The job was running relion using MPI (https://www2.mrc-lmb.cam.ac.uk/relion/index.php?title=Main_Page)

It caused waiters across the cluster, and caused the load to spike on NSDS on at a time.  When the spike ended on one NSD, it immediately started on another.

There were no obvious errors in the logs and the issues cleared immediately after the job was cancelled.

Has anyone else see any issues with relion using GPFS storage?
