607 Most important changes:
608 * Big speedup through lazy evaluation of the linear models
609 * Supernovae mode: Compile everything in one unit to improve inlining

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

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

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