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

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

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