Hi,
I found this thread from before Christmas, and I wondered what the
status of this problem is. We experience the same problems since our
upgrade to Scientific Linux 6.4, kernel 2.6.32-431.1.2.el6.x86_64, and
OpenMPI 1.6.5.
Users have reported severe slowdowns in all kinds of applications, like
VASP, OpenFOAM, etc.
Using the workaround '--bind-to-core' does only make sense for those
jobs, that allocate full nodes, but the majority of our jobs don't do that.
Is there any news on this issue?
Regards,
Bernd
