582 The "Simplicity does not preceed complexity, but follows it" release.
583 Most important changes:
584 * surf and simix modules reworked for simplification.
585 It lays the ground for future extensions and improvements of SimGrid
586 * SMPI was further improved, although not ready for production use yet.
588 On the way, we gained a bit more than 5% on the classical master/slave
589 example. More to come on this in future releases.

598 This dot release is mainly a maintenance one. Most important changes:
599 * We fixed a large amount of bugs all around
601 * We sanitized the way configuration is handled internally.
602 Try passing --cfg-help to binaries compiled against this version.
604 * SMPI is in better shape: lot of bugs fixing & usability improvements
605 It may be worth trying it (even if all bugs are not gone yet)
607 This version may have a bit more of memleaks than 3.3. This will be
608 fixed in a latter release.

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