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

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

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