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

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