Depends on how it is compiled. What NWCHEM_TARGET are you using? Quote:Rostov Mar 30th 3:20 am The doqmtests pass if I specify ARMCI_DEFAULT_SHMMAX=128, when running on one or several SMP nodes of 8 cores each (SMP RAM 24GB, though /proc/sys/kernel/shmmax value is 17179869184 or 16GB). Without the explicit specification, they fail.
