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

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

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