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