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

265 This dot release is mainly a maintenance one. Most important changes:
266 * We fixed a large amount of bugs all around
268 * We sanitized the way configuration is handled internally.

271 * SMPI is in better shape: lot of bugs fixing & usability improvements
272 It may be worth trying it (even if all bugs are not gone yet)
274 This version may have a bit more of memleaks than 3.3. This will be
275 fixed in a latter release.

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