I can see where it is allocating the correct amount of memory for the job per GPUs requested, but no other jobs will run on the node. If a value for “—mem” is defined, other jobs will share the node. Is this the expected behavior? I understand that when jobs do not request memory it is assumed that the job is running on the whole node, but here when we are asking for GPUs there is a default memory set with <font color="#000000" class="">DefMemPerGPU and it seems this is not being taken into account. Let me know if there is a reason for this behavior or if there is another way to set the default job memory.</font><div class=""><font color="#000000" class=""><br class=""></font></div><div class=""><font color="#000000" class=""><span style="caret-color: rgb(0, 0, 0);" class="">Config:</span></font></div><div class=""><font color="#000000" class=""><span style="caret-color: rgb(0, 0, 0);" class=""><div class="">SelectType=select/cons_tres</div><div class="">SelectTypeParameters=CR_Core_Memory,CR_CORE_DEFAULT_DIST_BLOCK</div><div class=""><div class="">PartitionName=p100 Nodes=ucs480 OverSubscribe=FORCE:4 DefCpuPerGPU=20 DefMemPerGPU=125000 Default=YES MaxTime=INFINITE State=UP</div></div><div class=""><br class=""></div><div class="">Node and job state when two jobs submitted with each requesting half the GPUs (no —mem specified):</div><div class=""><br class=""></div><div class=""><div class=""> CfgTRES=cpu=80,mem=500000M,billing=80</div><div class=""> AllocTRES=cpu=40,mem=250000M</div></div><div class=""><br class=""></div><div class="">Job state:</div><div class=""><div class="">JOBID PARTITION NAME USER ST TIME NODES NODELIST(REASON) </div><div class="">872 p100 test-s6 wayne.he PD 0:00 1 (Resources) </div><div class="">871 p100 test-s5 wayne.he R 0:03 1 ucs480</div></div></span></font></div></body></html>
