compiling PETSC with mvapich

[Randall Mackie]

I was able to run it on one processor, using the mpirun_rsh command as follows:

/usr/local/ofed/mpi/intel/mvapich-0.9.7-mlx2.2.0/bin/mpirun_rsh -np 1 hpcluster.local ./conftest

I am now running ./reconfigure.py as instructed.

What I don't understand is why the configure tool is unable to execute binaries created
with C.

Has anyone else used mvapich? (this is for use on infiniband).
