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