490 At least, after 2 years of hard work, we managed to release the 3.3
491 version of the SimGrid framework. There is so many changes that the
492 changelog only lists the most important ones, leaving alone the small
493 improvements, bug fixing and new gadgets.
497 * New simulation models, and improvement of the GTNetS wrapper
499 * Large memory savings (mainly in parser)
500 * Faster (twice faster is not uncommon, and from 20 hours to 2
501 minutes on very large scenarios)
502 * Much better scalability (tested up to 250,000 processes)
504 * Complete regression testing framework so that you can trust the tool
505 * Lot of neat new modules in the XBT toolbox
507 This version was thoroughly tested on linux 32bits and 64bits
508 (debian), as well as Mac OSX (leopard).
510 Unfortunately, our windows-guy left, and we cannot release the windows
511 version at the same time than the other archs. Any help would be
512 really welcomed here.
514 Some of the 96 included test suites are known to fail, but everything
515 should work anyway (don't panic):
516 * The amok module does not work in real deployment ATM, but I don't
517 see this as release critical since I'm not aware of anyone needing
519 * Some tests about the ability of GRAS to receive messages from
520 exotic platforms fail because I've lost access to these platforms
522 * the example/gras/pmm sometimes fails (about 1/10 of cases). I'm
523 quite puzzled, but I suspect a bug in the test, not in the lib.
524 * the tesh auto-tests "fail" on Mac OSX. This is because "rm -rf" is
525 sometimes too verbose (when the OS creates hidden files, I
526 suspect), but tesh definitely work as the rest on this arch.
528 We hope to manage to do more timely releases in the future, even if
529 that may turn out difficult since big stuff is coming (I don't say
530 much here for the suspense ;)
532 We hope you'll enjoy this new version, and please report any feedback
533 on the <simgrid-user@lists.gforge.inria.fr> list.
