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