[FRIAM] DARPA HPCS language implementations: Fortress and X10

[Marcus G. Daniels]

Hi,

Open source implementations of Fortress and X10 recently became 
available, and both build cleanly from source and seem to work.   
Fortress and X10 are implemented in Java, but X10 is introducing a new 
intermediate representation called Tucson which currently interpreted by 
a Java program.  I heard Chapel (the other HPCS language effort) will 
generate C++ code, but I haven't seen a code drop from Cray yet.  It's 
necessary to register with Sun to get access to their Subversion tree.
