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

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

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