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