78 The "Desktop Grid needs love too" release (also called "Xmas release").
79 Most important changes:
80 * Big speedup through lazy evaluation of the linear models
81 * Supernovae mode: Compile everything in one unit to improve inlining
82 * Simix network module for internal cleanups
83 * Load DAX of applications into SimDag
84 * Lot of small cleanups and other bug fixes

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

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

148 At least, after 2 years of hard work, we managed to release the 3.3
149 version of the SimGrid framework. There is so many changes that the
150 changelog only lists the most important ones, leaving alone the small
151 improvements, bug fixing and new gadgets.
155 * New simulation models, and improvement of the GTNetS wrapper
157 * Large memory savings (mainly in parser)
158 * Faster (twice faster is not uncommon, and from 20 hours to 2
159 minutes on very large scenarios)
160 * Much better scalability (tested up to 250,000 processes)
162 * Complete regression testing framework so that you can trust the tool
163 * Lot of neat new modules in the XBT toolbox
165 This version was throughfully tested on linux 32bits and 64bits
166 (debian), as well as Mac OSX (leopard).
168 Unfortunately, our windows-guy left, and we cannot release the windows
169 version at the same time than the other archs. Any help would be
170 really welcomed here.
172 Some of the 96 included test suites are known to fail, but everything
173 should work anyway (don't panic):
174 * The amok module does not work in real deployment ATM, but I don't
175 see this as release critical since I'm not aware of anyone needing
177 * Some tests about the ability of GRAS to receive messages from
178 exotic platforms fail because I've lost access to these platforms
180 * the example/gras/pmm sometimes fails (about 1/10 of cases). I'm
181 quite puzzled, but I suspect a bug in the test, not in the lib.
182 * the tesh auto-tests "fail" on Mac OSX. This is because "rm -rf" is
183 sometimes too verbose (when the OS creates hidden files, I
184 suspect), but tesh definitly work as the rest on this arch.
186 We hope to manage to do more timely releases in the future, even if
187 that may turn out difficult since big stuff is comming (I don't say
188 much here for the suspense ;)
190 We hope you'll enjoy this new version, and please report any feedback
191 on the <simgrid-user@lists.gforge.inria.fr> list.
