I'm trying to run a Phase Find Matches job using multiple processors but the -minRec 100 keeps resetting the number of processors for running the job to 1. I generated multiple phasedb subsets for the job but minRec still resets the processors to 1. Why is that? I would like to use all of my available processors.

What is probably happening here is that after the pre-screen against the database keys, you are left with 100 or fewer records to search. Such a search would take only a few seconds, and you would incur far more overhead if the job were to be split up over multiple processors.

You can override the -minRec option by running phase_dbsearch from the command line, but it should not be needed here.
