So are you new to MPI and Threading?  If you don't have at least some  
experience with parallel code development you could be jumping into  
the deep end (but don't let me discourage you)!  Here's some random  
questions you might consider before adopting a particular approach.

How long does each independent simulation run (seconds, minutes,  
hours)?  Is there a throughput or turn around time requirement?  What  
kinds of hardware are you going to run on (smp dual, quad, hex)?  Do  
you have access to other compute machines on the network where you'll  
run?  If distributed machines are available, can you ssh into them,  
are the machines homogeneous or heterogenous, do they have shared file  
systems?
