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

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