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