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