Hi- anyone know how to specify the number of processors to run phenix under in linux?  Or how to tell what the default is?  I'm running linux (fedora) with 4 processors and can't tell whether phenix is using all of them or not.  I do the refinement with .csh files and tried doing "myfile.csh --nproc=4".  The file ran but no faster- I can't tell if it is using 4 by default or if that's the incorrect command to specify the use of 4 processors.
Thanks for your help!
