Large system Hessian crash

Hello!

When computing the Hessian of a large molecule (469 atoms, 3514 basis functions) I am getting the following error:

Q-Chem fatal error occurred in module forms2/ShlPairs.C, line 54: In ~ShlPairs: s2Ints != 0.

I have tried increasing MEM_TOTAL and MEM_STATIC, as well as CPSCF_NSEG. Based on other slightly smaller frequency jobs i’ve run successfully, and assuming a scaling of O(N^2M/Nseg), where N=number of basis functions and M=number of atoms, I believe 800 GB should be sufficient for this job, but I might be wrong.

I am using QChem 6.2.0, and the following input:

Any insight into how to make compute a hessian for this system size would be much appreciated!

That should be the correct scaling but the memory scales per core. For large frequency jobs, we often request a full node (so that we can have all of its memory) but we don’t run on all processors (adjusting value of -nt flag).
