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