[petsc-users] about MPI

[Ethan Coon]

By default, PETSc doesn't put mpiexec in the path.

Try:

${PETSC_DIR}/${PETSC_ARCH}/bin/mpiexec -n ...

Assuming that works, you can put this directory, i.e.

$PETSC_DIR/$PETSC_ARCH/bin 

in your $PATH environmental variable, and just using "mpiexec" should
work fine then.
