Most important changes: * surf and simix modules reworked for simplification. It lays the ground for future extensions and improvements of SimGrid * SMPI was further improved, altrough not ready for production use yet. On the way, we gained a bit more than 5% on the classical master/slave example. More to come on this in future releases. _ _____ _____ _ __ _____ _ __ ___(_) ___ _ __ |___ / |___ / / | \ \ / / _ \ '__/ __| |/ _ \| '_ \ |_ \ |_ \ | | \ V / __/ | \__ \ | (_) | | | | ___) | ___) || | \_/ \___|_| |___/_|\___/|_| |_| |____(_)____(_)_| This dot release is mainly a maintainance one. Most important changes: * We fixed a large amount of bugs all around * We sanitized the way configuration is handled internally. Try passing --cfg-help to binaries compiled against this version. * SMPI is in better shape: lot of bugs fixing & usability improvements It may be worth trying it (even if all bugs are not gone yet) This version may have a bit more of memleaks than 3.3. This will be fixed in a latter release. ____ _ ____ _ _ / ___|(_)_ __ ___ / ___|_ __(_) __| | \___ \| | '_ ` _ \| | _| '__| |/ _` | ___) | | | | | | | |_| | | | | (_| | |____/|_|_| |_| |_|\____|_| |_|\__,_| _ _____ _____ __ _____ _ __ ___(_) ___ _ __ |___ / |___ / \ \ / / _ \ '__/ __| |/ _ \| '_ \ |_ \ |_ \ \ V / __/ | \__ \ | (_) | | | | ___) | ___) | \_/ \___|_| |___/_|\___/|_| |_| |____(_)____/ _ _ _ _ _ _ _ | |___ __ _ __| |_ ___ __| | | || | ' \| / -_) _` (_-< ' \/ -_) _` | \_,_|_||_|_\___\__,_/__/_||_\___\__,_| homepage: http://simgrid.gforge.inria.fr/ download: http://gforge.inria.fr/frs/?group_id=12 At least, after 2 years of hard work, we managed to release the 3.3 version of the SimGrid framework. There is so many changes that the changelog only lists the most important ones, leaving alone the small improvements, bug fixing and new gadgets. In short: * Java bindings * New simulation models, and improvement of the GTNetS wrapper * Large memory savings (mainly in parser) * Faster (twice faster is not uncommon, and from 20 hours to 2 minutes on very large scenarios) * Much better scalability (tested up to 250,000 processes) * Complete regression testing framework so that you can trust the tool * Lot of neat new modules in the XBT toolbox This version was throughfully tested on linux 32bits and 64bits (debian), as well as Mac OSX (leopard). Unfortunately, our windows-guy left, and we cannot release the windows version at the same time than the other archs. Any help would be really welcomed here. Some of the 96 included test suites are known to fail, but everything should work anyway (don't panic): * The amok module does not work in real deployment ATM, but I don't see this as release critical since I'm not aware of anyone needing this right now * Some tests about the ability of GRAS to receive messages from exotic platforms fail because I've lost access to these platforms (such as AIX) * the example/gras/pmm sometimes fails (about 1/10 of cases). I'm quite puzzled, but I suspect a bug in the test, not in the lib. * the tesh auto-tests "fail" on Mac OSX. This is because "rm -rf" is sometimes too verbose (when the OS creates hidden files, I suspect), but tesh definitly work as the rest on this arch. We hope to manage to do more timely releases in the future, even if that may turn out difficult since big stuff is comming (I don't say much here for the suspense ;) We hope you'll enjoy this new version, and please report any feedback on the list.
