Hi!
This patch removes number four of the copies done for guard update.
Basically, additionally to the three copies I mentioned in the previous
mail, we're doing one extra during the RemoteView expressionApply of the
data-parallel assignment we're doing for the guard domains. Ugh. Fixed by
manually sending/receiving from/to the views. Doesn't work for Cheetah,
so conditionalized on POOMA_MPI.
What breaks for Cheetah?
I don't remember... I can try again next week.
I tried again, and with Cheetah this is really a mess, because Cheetah
cannot receive into a View, so we need to pass a Brick as IncomingView and
a BrickView as View to SendReceive<IncomingView>::receive<View>() and this
breaks all over the place in the Cheetah library...
So, unfortunately, no - this doesn't work for Cheetah - at least not with
major surgery inside the Cheetah library (which I would rather drop than
fix).
So, is the patch ok as it is (affecting only POOMA_MPI)?
