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