OSG has limited support for multicore jobs. These can be used for threaded or OpenMP applications. To request a multicore slot, simply use the HTCondor request_cpus attribute in your submit file. Example:

request_cpus = 8

Multicore jobs can currently request up to 8 cores. Please note that you have to limit your code to the same number of cores. Do not use core auto-detection as it might detect cores not assigned to your job. If you request 8 cores from the scheduler, limit your code to 8 threads as well.

You can’t perform that action at this time.
