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

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

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