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