based on my reading PPC 7448 is basically the same processor in my
Apple PowerMac G4 <http://en.wikipedia.org/wiki/PowerPC_G4>.
Therefore, OpenMPI should have no trouble as I build OpenMPI on my G4
I have no idea where the MIPS references come from. PPC has always
meant PowerPC in everything I have seen. All MIPS chips I'm aware of
are labeled Rxxxx.
It might be best to get a PowerMac G4 and build OpenMPI on it, but
you'd probably have better luck if you install Linux on the G4 instead
of building OpenMPI on OS X as your final platform is Linux.
