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

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

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