Hi all,
I've decided to try some bench marking with respects to performance and given that I have plenty of memory to play with I thought I would start by preserving all of the integrals using SCF=InCore.
The way the cluster that I use works requires the Gaussian memory request to be in a separate "job" file. So the regular %mem is not present. Either way I specified 16GB. This caused Gaussian to crash complaining about not enough words. After speaking with our IT guys I used the command export GAUSS_MEMDEF=4000000000. This did the trick and I wasn't getting any error message with regards to memory.
However, I was getting the following error message:
Integral symmetry usage will be decided dynamically.
397174 words used for storage of precomputed grid.
Keep R1 ints in memory in canonical form, NReq=1352910536.
Contradictory integral options passed to UseFC.

Any thoughts of what this could be?
Thanks
