Allocatable memory on Marconi

Dear Users,

In a recent investigation we discovered an issue on the maximum amount of memory per node that can be asked on MARCONI, currently set at 123 GB. In some cases, asking for the full memory results in premature and unexpected job crashes. We found out that the correct maximum limit should be set at 118GB, and this new limit will be set as not superable on the next scheduled maintenance operation on Marconi (to be announced) . Meanwhile, we strongly recommend you to limit the maximum amount of allocatable memory per node in your jobscript to 118GB (#PBS mem=118GB), so that you can avoid eventual issues that may affect your job execution.

Best Regards,
