slurmstepd: error: *** JOB 733512 ON cn011 CANCELLED AT 2022-04-05T23:

Respected sir,
I am a beginner of molcas software. I am trying to run simple jobs where I am getting some error given in the subject.
In the error file, "job733512.err" the following lines showed up

The following have been reloaded with a version change:
  1) gcc/9.2.0 => gcc/10.2.0
  2) intel/2019.5.281 => intel/2020.2.254
  3) molcas/19.11 => molcas/19.11_Intel_2020

By looking at the error file, I guess there is a problem in the time limit. But how can I resolve that... How can I know how much time should be fixed here.

Thank you

6 hours should be more than enough for a SCF of water with minimal basis. There could be a problem with compilation, but:

1) 40 parallel processes is definitely overkill. Besides, each process will be using the amount of memory specified by MOLCAS_MEM (2GB by default). If you have 20 process per physical node, does each node have at least 40GB of RAM?

2) Do not run mpirun. Instead, just pass -np to pymolcas, or define the variable MOLCAS_NPROCS.

3) If you used a multithreaded BLAS/LAPACK library, you may want to define MOLCAS_THREADS too, otherwise each process may end up using all available cores...
