The job stats seems to be a really nice feature, but we are still on Lustre 2.1. I will look into it when we upgrade. I created a little python script that restructures the lltop output and identifies which jobs (and users) running on the nodes that hit the lustre file system hardest. It has been accepted into the contrib section of lltop, it only works for torque though. https://github.com/jhammond/lltop/tree/master/contrib/torque Again, thanks for the help and comments, Roy. r. _______________________________________________ Lustre-discuss mailing list Lustre-discuss@lists.lustre.org http://lists.lustre.org/mailman/listinfo/lustre-discuss
