Well, the way I understood the discussion was about how you can
utilize your new $$$ SAN boards well with your existing applications.
If you used something like MPI you just switch to a new implementation
optimized for your network (and hope the new one is compatible
with your code ;) )
Of course you can use some lower-level API and get better
performance, but your programs will undoubtedly be more complicated
and probably need to be rewritten for new APIs every now and then.
If you used sockets, I believe the normal way to use SAN boards
is to just make them look like network cards with a large MTU
Sure it works, but it's not very efficient :) (I have to admit
I've not played with that kind of toys at all, though)
