Comments on Data Parallel Languages

Extended message passing will “by definition” allow user to get very high performance
Not clear if penalty of using HPF like approach will be more than classical hope of “factor of two” -- need research and experimentation
- This is major goal of “fundamental research”
Certainly can move to a “library” like approach (such as Matlab today) with probably interpreted (Java) frontends as an interface to high performance optimized parallel runtime
