562 At least, after 2 years of hard work, we managed to release the 3.3
563 version of the SimGrid framework. There is so many changes that the
564 changelog only lists the most important ones, leaving alone the small
565 improvements, bug fixing and new gadgets.
569 * New simulation models, and improvement of the GTNetS wrapper
571 * Large memory savings (mainly in parser)
572 * Faster (twice faster is not uncommon, and from 20 hours to 2
573 minutes on very large scenarios)
574 * Much better scalability (tested up to 250,000 processes)
576 * Complete regression testing framework so that you can trust the tool
577 * Lot of neat new modules in the XBT toolbox
579 This version was thoroughly tested on linux 32bits and 64bits
580 (debian), as well as Mac OSX (leopard).
582 Unfortunately, our windows-guy left, and we cannot release the windows
583 version at the same time than the other archs. Any help would be
584 really welcomed here.
586 Some of the 96 included test suites are known to fail, but everything
587 should work anyway (don't panic):
588 * The amok module does not work in real deployment ATM, but I don't
589 see this as release critical since I'm not aware of anyone needing
591 * Some tests about the ability of GRAS to receive messages from
592 exotic platforms fail because I've lost access to these platforms
594 * the example/gras/pmm sometimes fails (about 1/10 of cases). I'm
595 quite puzzled, but I suspect a bug in the test, not in the lib.
596 * the tesh auto-tests "fail" on Mac OSX. This is because "rm -rf" is
597 sometimes too verbose (when the OS creates hidden files, I
598 suspect), but tesh definitely work as the rest on this arch.
600 We hope to manage to do more timely releases in the future, even if
601 that may turn out difficult since big stuff is coming (I don't say
602 much here for the suspense ;)
604 We hope you'll enjoy this new version, and please report any feedback
605 on the <simgrid-user@lists.gforge.inria.fr> list.
