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

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

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