[petsc-users] testing scalability for ksp/ex22.c

[Francis Poulin]

I don't seem to have the hydra in my bin folder but I do have petscmpiexec that I've been using.

Also, I want to install PetSc on an SGI machine that I have access to.  I have been told that using MPT would give better performance compared to mpich2.  When I configure petsc on this server I don't suppose

-with-mpi-dir=/opt/sgi/mpt

 the above would work because of the different name.  Do you have a suggestion as to what I could try?
