I've seen issues like this before, mainly related to the incorrect  
threading library being used (e.g. compiling with the Intel compiler..  
using gnu pthreads..).

I would check out which pthread libraries are being loaded when you  
run your code in the cluster environment..

As a check - are you able to successfully run some simple pthread code  
through SGE? Or even OpenMP code.
