I have a machine (machine1) with 96 CPUs. When I submit an abaqus job directly on this machine, the calculation time is about one and a half hours. However, when I submit it to this machine (machine1) through pbs and use the same number of CPUs to calculate the same job, it takes two and a half hours. How can I solve this performance problem?
Please check the below while running without openpbs and with openpbs
- system environment variables
- application environment variable
If you could share the application batch command line used with and without the scheduler.
