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