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

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

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