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