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

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

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