I thought it was condescending and missed the point, Gilad. But that's
no surprise, as Renato isn't an MPI guy, he's an InfiniBand guy. I
took him to task soon after that at a conference during a panel
session, and he understood Patrick's point much better after some back
and forth.

We know lots of ways to make MPI faster. InfiniBand is missing many of
them.
