Satish, the idiotic Sundials configure cannot find mpicc even when its
passed in as the C compiler:

MPI-C Settings
--------------
checking if using MPI-C script... yes
checking if absolute path to mpicc was given... no
checking for mpicc... none
   Unable to find a functional MPI-C compiler.
   Try using --with-mpicc to specify a MPI-C compiler script,
   --with-mpi-incdir, --with-mpi-libdir and --with-mpi-libs
   to specify the locations of all relevant MPI files, or
   --with-mpi-root to specify the base installation directory
   of the MPI implementation to be used.
   Disabling the parallel NVECTOR module and all parallel examples...

Do we have to give -with-mpicc as an argument?

  Thanks,

     Matt

experiments is infinitely more interesting than any results to which their
