[petsc-users] error with PAMI (fwd)

[Inge Gutheil]

Hello,
a user here in Juelich got the same error and he said he only got it on
BlueGene with PETSc, so I believe there is a problem with PAMI and PETSc
at least PETSc 3.3-p5. Im am just now installing PETSc 3.4.2 and want to
ask the user whether the problem still occurs. I also had thought of
posting it to the PETSc list but I do not have the complete error code,
the user only sent us the PAMI error, and it was exactely the same
place. If it is still there with PETSc 3.4.2, it might be a problem with
PAMI, but IBM won't help if we can't give them a small reproducible
example. Anyway, nice to hear that we are not alone in Juelich.

I would like to solve a non-linear system but as soon as the function SNESSolve is called the code crashes and I get the following error message (MooseMBFlow is the executable):
