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