220 On the way, we gained a bit more than 5% on the classical master/slave
221 example. More to come on this in future releases.

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

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