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