When defining the nodes in slurm.conf . For example, we have: # COMPUTE NODES NodeName=DEFAULT Sockets=2 ThreadsPerCore=2 State=UNKNOWN NodeName=str957-bl0-0[1-2] CoresPerSocket=6 Feature=ib,blade,intel NodeName=str957-bl0-0[3-5] CoresPerSocket=8 Feature=ib,blade,intel NodeName=str957-bl0-[15-16] CoresPerSocket=4 Feature=ib,nonblade,intel NodeName=str957-bl0-[17-18] CoresPerSocket=6 ThreadsPerCore=1 Feature=nonblade,amd NodeName=str957-bl0-[19-20] Sockets=4 CoresPerSocket=8 ThreadsPerCore=1 Feature=nonblade,amd NodeName=str957-mtx-[00-15] CoresPerSocket=14 Feature=ib,nonblade,intel
Here, the "Features" are what can be requested by --constraint= line. HIH. -- Diego Zuccato DIFA - Dip. di Fisica e Astronomia Servizi Informatici Alma Mater Studiorum - Università di Bologna V.le Berti-Pichat 6/2 - 40127 Bologna - Italy tel.: +39 051 20 95786
