IMPORTANT: memory limits on Marconi

Dear Users,

please pay attention to the amount of memory requested for your jobs on all Marconi partitions, which should be limited to:

Broadwell partitions: 118000M \ 115G  per node, or 3200M \ 3G per core

KNL partitions, cache\flat constraint: 86000M \  83G  [ + 16G HBM (MCDRAM) for flat nodes ]  

SKL partitions: 182000M \ 177G

For KNL and SKL partitions, working on exclusive nodes only, you can omit the memory specifications: by default the entire available memory will be assigned to jobs.

The request of memory in an amount larger than the available one caused many jobs to remain in queue on all Marconi partitions, with no possibility to run. We adjusted the memory for these jobs to let them start. 

Marconi user guide has been updated with the above limits.

Best regards
