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

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

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

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