248 It lays the ground for future extensions and improvements of SimGrid
249 * SMPI was further improved, although not ready for production use yet.
251 On the way, we gained a bit more than 5% on the classical master/slave
252 example. More to come on this in future releases.

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

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