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

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

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