The backtrace that you posted is from HP-MPI, definitely not MPICH2.   
You can tell by several different ways, including the function names  
("hpmp_*"), shared library name ("libmpi.so.1"), and the fact that the  
shared lib is installed in "/opt/hpmpi/".

If you wish to use MPICH2 instead, please check your $PATH and ensure  
that the MPICH2 installation "bin" dir is earlier in your path than  
the "/opt/hpmpi" utilities.  Also, make sure that you use the  
"mpicc" (and similar) compiler wrappers.
