There is a (very) rough cut of an EasyStar on gitorious: http://gitorious.org/ron-s-hanger/easystar-rc/ It can be had as a tarball from here: http://gitorious.org/ron-s-hanger/easystar-rc/archive-tarball/master The directory must be renamed "EasyStar" Ron ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
