Hi Guys, My users are reporting some issues with memory on our lustre 1.8.1 clients. It looks like when they submit a single job at a time the run time was about 4.5 minutes. However, when they ran multiple jobs (10 or less) on a client with 192GB of memory on a single node the run time for each job was exceeding 3-4X the run time for the single process. They also noticed that the swap space kept climbing even though there was plenty of free memory on the system. Could this possibly be related to the lustre client? Does it reserve any memory that is not accessible by any other process even though it might not be in use?
Thanks much, -J
