Foil 15 Remarks on HPJava -- Data Parallel Java - I

From Master Foilset Web Based Network Technologies for Scientific Computing CRPC NSF Review August 15-16 1996 -- 16 August 96. by Geoffrey C. Fox
Secs 106
As Java lies "inbetween" Fortran and C++, one can expect that data parallel Java can learn from corresponding HPF and HPC++ studies
"Parallel Compiler Runtime Consortium" produced a very rough draft
  • http://www.npac.syr.edu/users/gcf/hpjava3.html
Java does not support templates and STL approach of C++ not so natural
Need to recognize that performance of Objects in Java poorer than that of "simple types"
Java spans high level interpreted objects to low level optimally compiled "simple types"
