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