Current State of Java for HPC
At the last JavaOne I did a walk-on talk during the AMD keynote
where I talked about how incredible HotSpot's performance had
become - beating the best C compilers. I ended my talk with a
joking comment that "the next target is Fortran". Afterwards,
Denis
Caromel of
Inria came up to
me and said "you're already there". He and some colleges had been
working on some comparisons between Java and Fortran for HPC. Their
final report
Current State of Java for
HPC has been made available as a Tech Report and makes
pretty interesting reading. There are a lot of HPC micro benchmarks
in it which look great. Thanks!
