We're very cautious on the scientific compute clusters, only because when we went, I think it was, from 5.x to 6.x, or there were mathematical inconsistencies that *may* have been from glibc. Those seem to have been resolved, but they push back until they can verify the results via regression test. You *do* have a test system or cluster for them to regression test on, right...? mark
