132 The "Desktop Grid needs love too" release (also called "Xmas release").
133 Most important changes:
134 * Big speedup through lazy evaluation of the linear models
135 * Supernovae mode: Compile everything in one unit to improve inlining
136 * Simix network module for internal cleanups
137 * Load DAX of applications into SimDag
138 * Lot of small cleanups and other bug fixes

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

172 This dot release is mainly a maintenance one. Most important changes:
173 * We fixed a large amount of bugs all around
175 * We sanitized the way configuration is handled internally.
176 Try passing --cfg-help to binaries compiled against this version.
178 * SMPI is in better shape: lot of bugs fixing & usability improvements
179 It may be worth trying it (even if all bugs are not gone yet)
181 This version may have a bit more of memleaks than 3.3. This will be
182 fixed in a latter release.

204 At least, after 2 years of hard work, we managed to release the 3.3
205 version of the SimGrid framework. There is so many changes that the
206 changelog only lists the most important ones, leaving alone the small
207 improvements, bug fixing and new gadgets.
211 * New simulation models, and improvement of the GTNetS wrapper
213 * Large memory savings (mainly in parser)
214 * Faster (twice faster is not uncommon, and from 20 hours to 2
215 minutes on very large scenarios)
216 * Much better scalability (tested up to 250,000 processes)
218 * Complete regression testing framework so that you can trust the tool
219 * Lot of neat new modules in the XBT toolbox
221 This version was thoroughly tested on linux 32bits and 64bits
222 (debian), as well as Mac OSX (leopard).
224 Unfortunately, our windows-guy left, and we cannot release the windows
225 version at the same time than the other archs. Any help would be
226 really welcomed here.
228 Some of the 96 included test suites are known to fail, but everything
229 should work anyway (don't panic):
230 * The amok module does not work in real deployment ATM, but I don't
231 see this as release critical since I'm not aware of anyone needing
233 * Some tests about the ability of GRAS to receive messages from
234 exotic platforms fail because I've lost access to these platforms
236 * the example/gras/pmm sometimes fails (about 1/10 of cases). I'm
237 quite puzzled, but I suspect a bug in the test, not in the lib.
238 * the tesh auto-tests "fail" on Mac OSX. This is because "rm -rf" is
239 sometimes too verbose (when the OS creates hidden files, I
240 suspect), but tesh definitely work as the rest on this arch.
242 We hope to manage to do more timely releases in the future, even if
243 that may turn out difficult since big stuff is coming (I don't say
244 much here for the suspense ;)
246 We hope you'll enjoy this new version, and please report any feedback
247 on the <simgrid-user@lists.gforge.inria.fr> list.
