Information

The Molpro executable file is a script which already contains the srun command. Therefore, this command should not be added to your submission file.

Submission script for the CPU partition

molpro.slurm
#!/bin/bash
#SBATCH --nodes=1               # Number of nodes
#SBATCH --ntasks-per-node=20    # Number of MPI tasks per node
#SBATCH --cpus-per-task=2       # Number of OpenMP threads
#SBATCH --hint=nomultithread    # Disable hyperthreading
#SBATCH --job-name=molpro  # Jobname
#SBATCH --output=%x.o%j         # Output file %x is the jobname, %j the jobid
#SBATCH --error=%x.o%j          # Error file
#SBATCH --time=10:00:00         # Expected runtime HH:MM:SS (max 100h)

Comments:

  • All jobs have resources defined in Slurm per partition and per QoS (Quality of Service) by default. You can modify the limits by specifying another partition and / or QoS as shown in our documentation detailing the partitions and Qos.
  • For multi-project users and those having both CPU and GPU hours, it is necessary to specify the project accounting (hours allocation for the project) for which to count the job's computing hours as indicated in our documentation detailing the project hours management.
