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

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

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