Last month our clusters completed a century of work. This week we surpassed another milestone; 1 million compute hours.

Additionally last week for the first time in almost 3 years our users consumed 100% of available cores, a significant achievement

Today the sum total of work computed on our clusters since we started in 2010 surpassed 100 years. That's the equivalent of a fairly powerful processor working flat out for a century. While we've accumulated quite a large number of…

In anticipation of more users being added to the Hex cluster we have modified the scheduling rules. Previously there was an open policy:

USERCFG[DEFAULT] MAXJOB=180

USERCFG[DEFAULT] MAXPROC=180

USERCFG[DEFAULT] MAXNODE=180

This effectively allowed users to consume 66% of the cluster at
