217 * SMPI was further improved, although not ready for production use yet.
219 On the way, we gained a bit more than 5% on the classical master/slave
220 example. More to come on this in future releases.

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

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