194 The "Simplicity does not preceed complexity, but follows it" release.
195 Most important changes:
196 * surf and simix modules reworked for simplification.
197 It lays the ground for future extensions and improvements of SimGrid
198 * SMPI was further improved, although not ready for production use yet.
200 On the way, we gained a bit more than 5% on the classical master/slave
201 example. More to come on this in future releases.

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

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