The default Intel compilers will be changed to version 8.1
from 7.1. If you use the 7.1 compilers now and do not
recompile after the switch, you WILL HAVE to do a
"module load intel7.1-build20040708" inside your batch
scripts.

Unset MP_TASK_AFFINITY=MCM as a default. Found that MP_TASK_AFFINITY=MCM
and MEMORY_AFFINITY=MCM caused at least one user problem, and
MP_TASK_AFFINITY is reported to not behave properly for
multiple jobs on a node.
|
| September 9 |
Cheetah |
Making MP_TASK_AFFINITY=MCM a default settings. We already have
MEMORY_AFFINITY=MCM and MP_SHARED_MEMORY=YES as defaults.
This should slightly improve performance for most users.
