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

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

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