Now I have tested this mpiexec with a few configurations 
and none of them come out without error. 

When compiling with: --with-default-comm=mpich2-pmi 

Only a few errors appear during runtest.pl: 
mpiexec hello -sleep -abort 0 
mpiexec hello -sleep -abort 1 
mpiexec hello -sleep -abort 2 

I really don't know if this will be significant 
to my users, so I can not guarantee anything by 
installing this software. 

I guess that the Torque must be patched to work 
with this mpiexec. 
Conceptually this could have been a module in 
a PBS system and as such it woild have the 
missing link between pbs and mpi.
