197 Most important changes:
198 * surf and simix modules reworked for simplification.
199 It lays the ground for future extensions and improvements of SimGrid
200 * SMPI was further improved, although not ready for production use yet.
202 On the way, we gained a bit more than 5% on the classical master/slave
203 example. More to come on this in future releases.

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

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