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