438 At least, after 2 years of hard work, we managed to release the 3.3
439 version of the SimGrid framework. There is so many changes that the
440 changelog only lists the most important ones, leaving alone the small
441 improvements, bug fixing and new gadgets.
445 * New simulation models, and improvement of the GTNetS wrapper
447 * Large memory savings (mainly in parser)
448 * Faster (twice faster is not uncommon, and from 20 hours to 2
449 minutes on very large scenarios)
450 * Much better scalability (tested up to 250,000 processes)
452 * Complete regression testing framework so that you can trust the tool
453 * Lot of neat new modules in the XBT toolbox
455 This version was thoroughly tested on linux 32bits and 64bits
456 (debian), as well as Mac OSX (leopard).
458 Unfortunately, our windows-guy left, and we cannot release the windows
459 version at the same time than the other archs. Any help would be
460 really welcomed here.
462 Some of the 96 included test suites are known to fail, but everything
463 should work anyway (don't panic):
464 * The amok module does not work in real deployment ATM, but I don't
465 see this as release critical since I'm not aware of anyone needing
467 * Some tests about the ability of GRAS to receive messages from
468 exotic platforms fail because I've lost access to these platforms
470 * the example/gras/pmm sometimes fails (about 1/10 of cases). I'm
471 quite puzzled, but I suspect a bug in the test, not in the lib.
472 * the tesh auto-tests "fail" on Mac OSX. This is because "rm -rf" is
473 sometimes too verbose (when the OS creates hidden files, I
474 suspect), but tesh definitely work as the rest on this arch.
476 We hope to manage to do more timely releases in the future, even if
477 that may turn out difficult since big stuff is coming (I don't say
478 much here for the suspense ;)
480 We hope you'll enjoy this new version, and please report any feedback
481 on the <simgrid-user@lists.gforge.inria.fr> list.
