Prior to PSLF version 21_06, when many instances of PSLF are run in parallel by EnFuzionSP, very high CPU load was often observed on the compute node machines, along with very high numbers of CPU thread count. PSLF version 21_06 from GE provides a fix for this by limiting the number of CPU threads that PSLF may use. To use the fix requires a patch to the SSTOOLS plug-in for EnFuzionSP. Please contact support@axceleon.com for the patch.
