Multicore Jobs

Please note, the OSG has limited support for multicore jobs. Multicore jobs can be submitted for threaded or OpenMP applications. To request multiple cores (aka cpus) use the HTCondor request_cpus attribute in your submit file.


request_cpus = 8

We recommend requesting a maximum of 8 cpus.

Important considerations

When submitting multicore jobs please note that you will also have to tell your code or application to use the number of cpus requested in your submit file. Do not use core auto-detection as it might detect more cores than what were actually assigned to your job.

MPI Jobs

For jobs that require MPI, see our OpenMPI Jobs guide.
