-ftree-parallelize-loops=~NPROC

This is a precompilation flag for fortran that tells the compiler to make your loops parrallelize over this many processors locally.

NOTE unless you are using the [[How to do simple parallelise loops on single node machines - concurrent|concurrent]] command, this can result potentially in some do loops breaking. (SPH - testing pending)
