I sorry i am of no help since we received our new cluster here and i  
am no longer working
on the Mac for now on.

But to me, OpenMp is a working option on the Mac.


OpenMP (Shared Memory Multiprocessing):

These tools compile code optimized for dual processors based on  
OpenMP directives. SMP is much easier to learn, compared to MPI .. so  
this could be useful to some. Get the latest version (1.6) of Omni MP  
compiler source and install. You should have no problems. Or get my  
binary distribution. To install, gunzip openmp-bin.tar.gz (if your  
browser didn't do so already) and then sudo tar -xvf openmp-bin.tar - 
C / and you are done! It installs OpenMP in /usr/local/openmp/. If  
you are interested in a tool that auto-parallelizes your code, click  
here.
