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

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

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