363 example. More to come on this in future releases.

382 fixed in a latter release.

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