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