[Beowulf] mpich2 and mpiexec from Ohio SC

 Good question!

 It does hang as well with the mpich2's own mpiexec, so I guess the
problem is not with mpiexec from OSC ...

 Any suggestions on what can be wrong?

 The system is 64-bit CentOS, with 2.4.21-32.ELsmp kernel. The
compilers were gcc and Intel Fortran 9.0, both in 64 bits.
