Please do. I'm glad it's being so useful - it seems to be hitting a
surprising amount of bugs of different origins.
It might be an idea to make it test a variety of arrays sizes and block
sizes, it was interesting to me that this showed up with 3x3 blocks, but
not 2x2 blocks.
I found the problem in MPICH, but i don't know how it relates to OpenMPI --
