General technical issue about running nwchem job using computer clusters


Clicked A Few Times
Hi,

I'm using compute cluster to run the job, but always encounter the following warning.
It seems that my registerable memory is too low. But it's not a large job to calculate.
Are there anyone having this kind of problem before?





module: loading 'openmpi/1.6.2'
module: loading 'nwchem/6.1.1'


WARNING: It appears that your OpenFabrics subsystem is configured to only
allow registering part of your physical memory. This can cause MPI jobs to
run with erratic performance, hang, and/or crash.

This may be caused by your OpenFabrics vendor limiting the amount of
physical memory that can be registered. You should investigate the
relevant Linux kernel module parameters that control how much physical
memory can be registered, and increase them to allow registering all
physical memory on your machine.

See this Open MPI FAQ item for more information on these Linux kernel module
parameters:

   http://www.open-mpi.org/faq/?category=openfabrics#ib-locked-pages

 Local host:              node241
Registerable memory: 65536 MiB
Total memory: 98292 MiB

Your MPI job will continue, but may be behave poorly and/or hang.
