nwchem 6.6 tests fails with more than 16 cores


Just Got Here
Hello there

I'm trying to run the tests inside the 'QA' directory and am facing strange issues.
I can only run the tests (e.g. doafewqmtests.mpi) with 16 or less cores, otherelse it fails with the following error:

_shm_create: shm_unlink: Permission denied
[18] Received an Error in Communication: (-1) _shm_create: shm_unlink
application called MPI_Abort(comm=0x84000000, -1) - process 18

The system in question is the following:
OS: centos 6.5
CC / FC / CXX = intel 16.0.2
MPI = impi 5.1.3
BLAS = mkl 11.3

Here's how I compiled nwchem:

$ make -C src/ nwchem_config

$ make -C src/


The *FLAGS_FOR_GA env variables were needed to get to this point

Ulimits are ok, AFAICT.


Any idea what is the cause of the problem?

TIA,
Fabricio

What is the output of the command

ls -lH /dev/shm

What about
ls -lrt /run/ | grep shm

No such directory as '/run' in centos 6.x

'ls -lrt /var/run/ | grep shm' also shows nothing, and nothing in '/tmp' too.
