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