31 The "Desktop Grid needs love too" release (also called "Xmas release").
32 Most important changes:
33 * Big speedup through lazy evaluation of the linear models
34 * Supernovae mode: Compile everything in one unit to improve inlining
35 * Simix network module for internal cleanups
36 * Load DAX of applications into SimDag
37 * Lot of small cleanups and other bug fixes

54 The "Simplicity does not preceed complexity, but follows it" release.
55 Most important changes:
56 * surf and simix modules reworked for simplification.
57 It lays the ground for future extensions and improvements of SimGrid
58 * SMPI was further improved, altrough not ready for production use yet.
60 On the way, we gained a bit more than 5% on the classical master/slave
61 example. More to come on this in future releases.

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

101 At least, after 2 years of hard work, we managed to release the 3.3
102 version of the SimGrid framework. There is so many changes that the
103 changelog only lists the most important ones, leaving alone the small
104 improvements, bug fixing and new gadgets.
108 * New simulation models, and improvement of the GTNetS wrapper
110 * Large memory savings (mainly in parser)
111 * Faster (twice faster is not uncommon, and from 20 hours to 2
112 minutes on very large scenarios)
113 * Much better scalability (tested up to 250,000 processes)
115 * Complete regression testing framework so that you can trust the tool
116 * Lot of neat new modules in the XBT toolbox
118 This version was throughfully tested on linux 32bits and 64bits
119 (debian), as well as Mac OSX (leopard).
121 Unfortunately, our windows-guy left, and we cannot release the windows
122 version at the same time than the other archs. Any help would be
123 really welcomed here.
125 Some of the 96 included test suites are known to fail, but everything
126 should work anyway (don't panic):
127 * The amok module does not work in real deployment ATM, but I don't
128 see this as release critical since I'm not aware of anyone needing
130 * Some tests about the ability of GRAS to receive messages from
131 exotic platforms fail because I've lost access to these platforms
133 * the example/gras/pmm sometimes fails (about 1/10 of cases). I'm
134 quite puzzled, but I suspect a bug in the test, not in the lib.
135 * the tesh auto-tests "fail" on Mac OSX. This is because "rm -rf" is
136 sometimes too verbose (when the OS creates hidden files, I
137 suspect), but tesh definitly work as the rest on this arch.
139 We hope to manage to do more timely releases in the future, even if
140 that may turn out difficult since big stuff is comming (I don't say
141 much here for the suspense ;)
143 We hope you'll enjoy this new version, and please report any feedback
144 on the <simgrid-user@lists.gforge.inria.fr> list.
