Comment (by hinder):

 I didn't mean that; I wanted to be able to specify the number of MPI
 processes and have simfactory calculate the number of threads based on its
 knowledge.  So if I said "--processes 1", on LoneStar it would give me one
 process with 6 threads bound to one processor, and if i said "--processes
 2", it would give me two processes, each with 6 threads bound to the
 respective processor.  i.e. I think my request is now for an additional
 option (without changing any existing interface) to directly specify the
 number of MPI processes instead of the total number of threads.  My
 obvious use-case is for test suites, which care about the number of
 processes.
