Hi, sorry for the late reply, I was busy w/ end of FY purchases. Attached are 2 files: cpu_arch. list - the CPU info for each compute node. err. log - sorted result of a egrep 'setaff|compute' on the job log files, each log file lists</div>

Typically, this is caused by a non-standard CPU situation on your node. Are all tests being run on the same node or is there a pattern on the nodes that see failure? Can you send us the info from
