CCSD(T) Calculation with Quadruple Zeta Basis Set -- Memory Issue

Clicked A Few Times
Thank you, Edoapra.

I managed to get more core (20 nodes, 400 cores) so I was able to run without MA allocation issue with the following memory line:

memory stack 1000 mb heap 200 mb global 4400 mb


Everything else in the input file is identified as in your previous comment. It took about 5 mins for the calculation to go to

tce_ao2e: fast2e=1
half-transformed integrals in memory

2-e (intermediate) file size = 105684005025
2-e (intermediate) file name = ./vim.v2i
Cpu & wall time / sec 144.8 184.8

tce_mo2e: fast2e=1
2-e integrals stored in memory

but the calculation has been hanging there for over eight hours -- nothing got written into the folder or output file at all. I also noticed there were some vim.aoints.x files that seem to have not been cleaned up properly. Is the behavior normal for this size of a calculation or this QZ calculation is pushing the limit of NWChem?

Thanks again.
