If you're really desperate you can hack the MVAPICH
sources and remove the code that sets CPU affinity.

Also if SGE supports CPU sets in the same way that
Torque does then get it to use those, that will trump
the setaffinity().

Alternatively could you switch to OpenMPI instead ?

We found it gives far better error messages as an
added bonus when we switched to it.

cheers,
Chris
