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

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