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

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

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