Ibán, What are you using for your scheduler?
On my compute nodes, I am setting the pagepool to 16 GB and setting aside specialized memory for GPFS that will not be allocated to jobs. -- Mike Jarsulic Associate Director, Scientific Computing Center for Research Informatics | Biological Sciences Division University of Chicago 5454 South Shore Drive, Chicago, IL 60615 | (773) 702-2066 From: gpfsug-discuss <[email protected]> on behalf of Iban Cabrillo <[email protected]> Date: Friday, March 8, 2024 at 8:44 AM To: gpfsug-discuss <[email protected]> Subject: [gpfsug-discuss] pagepool Good afternoon, We are new to the DSS system configurations. Reviewing the configuration I have seen that the default pagepool is set to this value: pagepool 323908133683 But not only in the DSS servers, but also in the rest of the HPC nodes ZjQcmQRYFpfptBannerStart External: Use caution with links, attachments, and providing information. <https://us-phishalarm-ewt.proofpoint.com/EWT/v1/MvNZe7V6M35iZPhbgng-hfU!9jECkqdfV_6Ic3NHXjlbIhrBhB3hwIztWE3CyPV6abEs3lGpxOjkRYIAc9f1p9-m8iXypBQN9kyE2G7S4g_sF2IPGxTSiOuvB1zZG9lqRzCpX3lnwnuoF6rsi0lN1pk$> Report Suspicious <https://us-phishalarm-ewt.proofpoint.com/EWT/v1/MvNZe7V6M35iZPhbgng-hfU!9jECkqdfV_6Ic3NHXjlbIhrBhB3hwIztWE3CyPV6abEs3lGpxOjkRYIAc9f1p9-m8iXypBQN9kyE2G7S4g_sF2IPGxTSiOuvB1zZG9lqRzCpX3lnwnuoF6rsi0lN1pk$> ZjQcmQRYFpfptBannerEnd Good afternoon, We are new to the DSS system configurations. Reviewing the configuration I have seen that the default pagepool is set to this value: pagepool 323908133683 But not only in the DSS servers, but also in the rest of the HPC nodes and I don't know if it is an excessive value. We are noticing that some jobs are dying by "Memory cgroup out of memory: Killed process XXX", and my doubt is if this pagepool is reserving too much memory for the mmfs process in decripento of the execution of jobs.
