599 At least, after 2 years of hard work, we managed to release the 3.3
600 version of the SimGrid framework. There is so many changes that the
601 changelog only lists the most important ones, leaving alone the small
602 improvements, bug fixing and new gadgets.
606 * New simulation models, and improvement of the GTNetS wrapper
608 * Large memory savings (mainly in parser)
609 * Faster (twice faster is not uncommon, and from 20 hours to 2
610 minutes on very large scenarios)
611 * Much better scalability (tested up to 250,000 processes)
613 * Complete regression testing framework so that you can trust the tool
614 * Lot of neat new modules in the XBT toolbox
616 This version was thoroughly tested on linux 32bits and 64bits
617 (debian), as well as Mac OSX (leopard).
619 Unfortunately, our windows-guy left, and we cannot release the windows
620 version at the same time than the other archs. Any help would be
621 really welcomed here.
623 Some of the 96 included test suites are known to fail, but everything
624 should work anyway (don't panic):
625 * The amok module does not work in real deployment ATM, but I don't
626 see this as release critical since I'm not aware of anyone needing
628 * Some tests about the ability of GRAS to receive messages from
629 exotic platforms fail because I've lost access to these platforms
631 * the example/gras/pmm sometimes fails (about 1/10 of cases). I'm
632 quite puzzled, but I suspect a bug in the test, not in the lib.
633 * the tesh auto-tests "fail" on Mac OSX. This is because "rm -rf" is
634 sometimes too verbose (when the OS creates hidden files, I
635 suspect), but tesh definitely work as the rest on this arch.
637 We hope to manage to do more timely releases in the future, even if
638 that may turn out difficult since big stuff is coming (I don't say
639 much here for the suspense ;)
641 We hope you'll enjoy this new version, and please report any feedback
642 on the <simgrid-user@lists.gforge.inria.fr> list.
