Dave Patterson and his group are primarily researching I/O these days
(Patterson coined the term "RISC" and the RISC-1 and RISC-2 projects at
U.C. Berkeley eventually turned into the Sparc).
I expect that more and more research work will turn to the problems of
how to design cheap memory systems that deliver supercomputer performance,
and how to increase I/O bandwidth, and there's no reason that this should
cost $20M (though initially it won't be cheap).
