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