Let's not forget that Brian is not only an MPI developer (i.e., a  
network programmer), he's also a customer.

If OpenFabrics only wants the HPC market, you can probably ignore this  
entire thread.  The OpenFabrics-based MPI's will hobble along like  
they have been.  If you want larger markets, it's probably pretty safe  
to assume that Brian's reactions are going to be quite similar to  
enterprise network programmers.

To be clear: it's not just verbs education (books, tutorials, FAQ's,  
etc.) that is required to win the hearts and minds of enterprise  
network programmers.  You also need a network API that is no more  
complex than common sockets usage.    Verbs -- and the additional  
baggage that it requires for performance, like registration caches and  
memory allocation hooking -- does not currently meet this requirement.
