238 It lays the ground for future extensions and improvements of SimGrid
239 * SMPI was further improved, although not ready for production use yet.
241 On the way, we gained a bit more than 5% on the classical master/slave
242 example. More to come on this in future releases.

251 This dot release is mainly a maintenance one. Most important changes:
252 * We fixed a large amount of bugs all around
254 * We sanitized the way configuration is handled internally.
255 Try passing --cfg-help to binaries compiled against this version.
257 * SMPI is in better shape: lot of bugs fixing & usability improvements
258 It may be worth trying it (even if all bugs are not gone yet)
260 This version may have a bit more of memleaks than 3.3. This will be
261 fixed in a latter release.

283 At least, after 2 years of hard work, we managed to release the 3.3
284 version of the SimGrid framework. There is so many changes that the
285 changelog only lists the most important ones, leaving alone the small
286 improvements, bug fixing and new gadgets.
290 * New simulation models, and improvement of the GTNetS wrapper
292 * Large memory savings (mainly in parser)
293 * Faster (twice faster is not uncommon, and from 20 hours to 2
294 minutes on very large scenarios)
295 * Much better scalability (tested up to 250,000 processes)
297 * Complete regression testing framework so that you can trust the tool
298 * Lot of neat new modules in the XBT toolbox
300 This version was thoroughly tested on linux 32bits and 64bits
301 (debian), as well as Mac OSX (leopard).
303 Unfortunately, our windows-guy left, and we cannot release the windows
304 version at the same time than the other archs. Any help would be
305 really welcomed here.
307 Some of the 96 included test suites are known to fail, but everything
308 should work anyway (don't panic):
309 * The amok module does not work in real deployment ATM, but I don't
310 see this as release critical since I'm not aware of anyone needing
312 * Some tests about the ability of GRAS to receive messages from
313 exotic platforms fail because I've lost access to these platforms
315 * the example/gras/pmm sometimes fails (about 1/10 of cases). I'm
316 quite puzzled, but I suspect a bug in the test, not in the lib.
317 * the tesh auto-tests "fail" on Mac OSX. This is because "rm -rf" is
318 sometimes too verbose (when the OS creates hidden files, I
319 suspect), but tesh definitely work as the rest on this arch.
321 We hope to manage to do more timely releases in the future, even if
322 that may turn out difficult since big stuff is coming (I don't say
323 much here for the suspense ;)
325 We hope you'll enjoy this new version, and please report any feedback
326 on the <simgrid-user@lists.gforge.inria.fr> list.
