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 -- > the darray bug is one I introduced on tuesday, so OpenMPI's ROMIO code > should not have a problem with this darray type. Fascinating! Richard
