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

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

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