Dear users,
in a short time a new configuration of queues will be available on Marconi cluster.
We try to summarize for you the main features and limits that will be imposed on them. All the details will be available on the online user guide to Marconi.  
For knldebug e knlprod queues, it will be possibile require only numa resources of “snc2” type and “cache/flat” mcdram. In order to test other types of numa (quadrant, hemisphere, snc4) we can use knltest queue that is subject to prior authorization.
The maximum number of cpus that you can require for the standard production (flat/cache mcdram and snc2 numa) is 68000 (1000 nodes) and wall time 24 hours. For the specific production (on the knltest queue, with “flat/cache” mcdram and “quadrant/hemisphere/snc4” numa) you can require up to 4896 cpus and 24 hours.
In order to install this new configuration in the upcoming hours the knl nodes of Marconi could be on offline status and not be available to run your jobs.
We let you know when all these configuration changes will be active.
Best regards,
HPC User Support @CINECA
