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

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

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