Ralph,

I mentioned at dinner how much I like listening to UCB Prof. Kathy Yelick's lectures.  Here's some slides I found of hers.  She is also associate lab director of NERSC at LBNL.

Here's the UCB web page about their view of HPC/Parallel computing.

I think the one-way (DMA) messaging model is very important, especially when it can be hidden and automatically (and correctly) done by the compiler (requires new languages?).

Any time you get a chance to hear her (or invite her to speak) you will enjoy it.  The work they are doing there will inform you to benefit your own work.
