EXTERNAL: Re: Problems using external packages Spooles and Hy pre with PETSc v2. 3.1

[Stephen R Ball]

Hi

Your example runs OK, as do some of my other problems. But with some
problems
PETSc v2.3.1 fails while PETSc v2.3.0 works. I have attached the output from
both PETSc versions for one of these problems. If you are interested,
perhaps
we could make arrangements for me sending you one of these problems.

Regards

Stephen

May I have the complete error message after the crash?
Can you run
~petsc/src/ksp/ksp/examples/tutorials/ex5.c
with the cmd:

mpirun -np 2 ./ex5 -ksp_type preonly -pc_type lu -mat_type aijspooles?
