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

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

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