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

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

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