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

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

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