Ok, thanks. I usually run these test with 4 or 8, but the major item is that atomicity is one of the areas that are not well supported in ompio (along with data representations), so a failure in those tests is not entirely surprising . Most of the work to support atomicity properly is actually in place, but we didn't have the manpower (and requests to be honest) to finish that work.
