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

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