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

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