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