The problem is most likely a difference in mpi libraries that namd2 was
compiled with and the ones used at runtime on the larger machine.
I have this issue all the time with icc8.0 and icc8.1 compilations.
If you cant compile against the current libs on the larger machine, then
try exporting your LD_LIBRARY_PATH in your batch script.
