I used the following as MACHINE file for a multiprocessor SGI
machine using mpich (which still uses SGI compilers). I encountered some
problems with SGI specific Machine file (I do not recollect the exact
details), especially related to running them through script. I found that
this results in some 4% slowness, never-the-less works well.
Best wishes,
