578 The "Desktop Grid needs love too" release (also called "Xmas release").
579 Most important changes:
580 * Big speedup through lazy evaluation of the linear models
581 * Supernovae mode: Compile everything in one unit to improve inlining
582 * Simix network module for internal cleanups
583 * Load DAX of applications into SimDag
584 * Lot of small cleanups and other bug fixes

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

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

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