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