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

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

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