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

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

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