8 This dot release is mainly a maintainance one. Most important changes:
9 * We fixed a large amount of bugs all around
11 * We sanitized the way configuration is handled internally.
12 Try passing --cfg-help to binaries compiled against this version.
14 * SMPI is in better shape: lot of bugs fixing & usability improvements
15 It may be worth trying it (even if all bugs are not gone yet)
17 This version may have a bit more of memleaks than 3.3. This will be
18 fixed in a latter release.

40 At least, after 2 years of hard work, we managed to release the 3.3
41 version of the SimGrid framework. There is so many changes that the
42 changelog only lists the most important ones, leaving alone the small
43 improvements, bug fixing and new gadgets.
47 * New simulation models, and improvement of the GTNetS wrapper
49 * Large memory savings (mainly in parser)
50 * Faster (twice faster is not uncommon, and from 20 hours to 2
51 minutes on very large scenarios)
52 * Much better scalability (tested up to 250,000 processes)
54 * Complete regression testing framework so that you can trust the tool
55 * Lot of neat new modules in the XBT toolbox
57 This version was throughfully tested on linux 32bits and 64bits
58 (debian), as well as Mac OSX (leopard).
60 Unfortunately, our windows-guy left, and we cannot release the windows
61 version at the same time than the other archs. Any help would be
64 Some of the 96 included test suites are known to fail, but everything
65 should work anyway (don't panic):
66 * The amok module does not work in real deployment ATM, but I don't
67 see this as release critical since I'm not aware of anyone needing
69 * Some tests about the ability of GRAS to receive messages from
70 exotic platforms fail because I've lost access to these platforms
72 * the example/gras/pmm sometimes fails (about 1/10 of cases). I'm
73 quite puzzled, but I suspect a bug in the test, not in the lib.
74 * the tesh auto-tests "fail" on Mac OSX. This is because "rm -rf" is
75 sometimes too verbose (when the OS creates hidden files, I
76 suspect), but tesh definitly work as the rest on this arch.
78 We hope to manage to do more timely releases in the future, even if
79 that may turn out difficult since big stuff is comming (I don't say
80 much here for the suspense ;)
82 We hope you'll enjoy this new version, and please report any feedback
83 on the <simgrid-user@lists.gforge.inria.fr> list.
