Cannot allocate memory


Clicked A Few Times
I was running NMR calcuation for a large system on the Owens cluster with NWChem 6.6 and 6.8. (~100 atoms) However, the job failed with the following message (which appered after "Creening Tolerance Information"):
--
Last System Error Message from Task 5:: Bad address
Last System Error Message from Task 36:: Cannot allocate memory
...
--

According to previous discussion, I set ARMCI_DEFAULT_SHMMAX 4096 but the error still showed up.
However, the same calculation works fine with 6.1 but t failed at the convergence of CPHF. I was wondering if there a way to solve this problem.


p.s. I also sucessfully run the same calcuation for a smaller system with NWChem 6.6 and 6.8. (~20 atoms)

Thank you in advance for your help.

HOMO/LUMO gap drops below (HL_TOL): 1.00D-02
DIIS, if invoked, will attempt to extrapolate

         using up to (NFOCK): 10 stored Fock matrices.
