It certainly wasn't tested because it didn't work in 3.0.0. I thought I had fixed it when I eliminated some errors pre-3.1 and got correct results on 2 procs with bs=1, but there were still lingering bugs since I clearly forgot to test it on a real problem. I've fixed these and added -vecscatter_window to runex19_5 in 3.1 so that it is tested and not necessarily broken (indeed, I think it is correct now). Jed
