Dear MRCC forum,
I am getting "Fatal error in exec scf" when I try to run a calculation with OpenMP parallelization. I give the example MINP file below. This has been tested for both the binary provided as well as MRCC compiled from source with Intel compilers (see module list provided below) and get error for both cases. When I run in serial or with MPI, the calculation works with no problem, only when I run with OpenMP. Also, the calculations seem to work with def2-SVP basis set. I would like to be able to utilise OpenMP parallelization since these calculations feed into LNO-CCSD(T) calculations, which only work with OpenMP parallelization.
MINP file:
Code:
basis=def2-tzvpp
calc=DF-HF
verbosity=3
mem=180GB
symm=off
unit=angs
geom=xyz
