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

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