Hans Zima, principal scientist at the Jet Propulsion
Laboratory (Pasadena, Calif.), said he started working with two top
Cray engineers in July to define a high-level programming language
</quote>

Zima said the new language will help software developers exploit both
parallel programming techniques and the locality of data in a large
clustered system.

Ada would be a perfect fit.  Ada already has tasking built-in for
intra-node communications, and it has a Distributed Systems Annex for
inter-node communications.  I think that creating an optimised Ada
run-time environment for massively parallel supercomputers is both
feasible and highly desirable.

Furthermore, I think Cray's input into the Ada revision process would
be extremely valuable; perhaps some extensions to the standard would
help get the most out of NUMA architectures.

Is DARPA listening? They're paying for all this, after all.  Now is
the time to reap the benefits of all the US taxpayer money that went
into Ada in the 1970's and 1980's.

GNAT on Crays anyone?
