570 At least, after 2 years of hard work, we managed to release the 3.3
571 version of the SimGrid framework. There is so many changes that the

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