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

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