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

389 fixed in a latter release.

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