Lately we've deployed 9 new =t3wn5[1-9]= servers featuring [[http://ark.intel.com/products/81060/Intel-Xeon-Processor-E5-2698-v3-40M-Cache-2_30-GHz][64 CPU cores]] / 128GB RAM / 10Gbs cards ; they're already fully exploited by the T3 user jobs as you can easily check by :

no action is required in order to get the jobs running there, actually these servers will be transparently selected by the batch system with higher preference

as a consequence of this CPU cores increase the T3 Steering Board will review the current [[Tier3Policies#Batch_system_policies][Batch System Policies]] in the next future by ( probably ) slightly raise the max allowed jobs thresholds per T3 user in each queue.
