324 example. More to come on this in future releases.

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

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