this is a bit of a strange question but I have tried almost everything that comes to mind to no avail:
I have compiled QE 6.4.1 and EPW 5.1.0
Code: Select all
Program EPW v.5.1.0 starts on 14Aug2019 at 5:12:43
This program is part of the open-source Quantum ESPRESSO suite
for quantum simulation of materials; please cite

Parallel version (MPI), running on 32 processors
I can run qe interactively or from my PBS pro schedule without problem but I can only run EPW interactively; If I try to run it via qsub (even though it runs on the same physical machine) it crashes with the following
Code: Select all
forrtl: severe (174): SIGSEGV, segmentation fault occurred

I have checked that the executable and mpirun are the same in both cases

/usr/local/intel/compilers_and_libraries_2019.0.117/linux/mpi/intel64/bin/mpiruI wonder if anyone else has had a problem like this - any hint would be appreciated!
Best,
