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

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