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

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

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