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

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