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