358 * SMPI is in better shape: lot of bugs fixing & usability improvements
359 It may be worth trying it (even if all bugs are not gone yet)
361 This version may have a bit more of memleaks than 3.3. This will be
362 fixed in a latter release.

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