Hi,

Which argument should I pass to pass to compile petsc on hopper II with superlu_dist, hypre and mumps (download) ? Without external package --with-mpi=0 works fine but then the external packages complain about it (no mpi specified). I tried to use and also modify the arch-cray-xt5-opt.py configure file but I did not go through it yet (Invalid mpiexec specified: /usr/common/acts/PETSc/3.0.0/bin/mpiexec.aprun). Instead of wasting time, I guess you guys will provide an answer pretty quickly.

Satish,

Why does --with-mpiexec have to be set on hopper? And why to this crazy location that may not always exist? Requiring the user to set this beast to some strange thing at configure time is not reasonable. We need a model that doesn't require strange knowledge like this.

The explanation for the strange thing in arch-cray-xt5-opt.py is: I started off with a reconfigure.py file from a prior install by nersc folks - so had some of this stuff in from there. [mpiexec.aprun is a derivative of one of the scripts we have in PETSC_DIR/bin/mpiexec.*]

Looks like --with-mpiexec=/bin/false would also work on this machine.

currently mpiexec is checked by configure primarily for for 'make test' stuff and 'check-mpi-shared' test.

We now have --with-batch=1 that generally works for machines where things can't be run directly. Here - on cray - configure seem to work directly - without batch - and without mpiexec.

Perhaps we can have configure - not abort if 'mpiexec' not found?

Sounds good. Have it not abort. perhaps a warning message? perhaps not no warning message needed. Barry
