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