PBS on Marconi KNL: change of configuration

Dear Users,

we inform you that a change in the configuration of the PBS on Marconi KNL partition is in place. The maximum number of cpus that can be requested on a KNL node is 68, corresponding to the number of physical cores (ncpus=68). This new change in PBS configuration prevents memory over-allocation leading to jobs and nodes failure. Please also note that hyperthreading is still in place and you can use up to 272 MPI processes/threads in your job.

Best Regards,
