[petsc-users] PETSc problems with MVAPICH2

[Wadud.Miah at awe.co.uk]

Hello,

I have built PETSc 3.4.2 with MVAPICH2 1.9b and my application code crashes when I spawn it with 16 processes; it works with 4 and 8 processes. This occurs at the MatAssemblyEnd subroutine when the non-local values are broadcast to other processes. Has anyone else had issues with MVAPICH2?

Regards,
Wadud.
