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

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

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