Currently, Altix (sn2) does not have a ptc.g that spans nodes. We have our own tlb purge mechanism which is very flexible and scalable. Maybe it would be best to follow that example. To repeat Bjorn's comments, this area can be fraught with _VERY_ difficult to diagnose problems. A boot test can hardly be expected to uncover all the races so be patient while we walk through this code.
