139 The "Desktop Grid needs love too" release (also called "Xmas release").
140 Most important changes:
141 * Big speedup through lazy evaluation of the linear models
142 * Supernovae mode: Compile everything in one unit to improve inlining
143 * Simix network module for internal cleanups
144 * Load DAX of applications into SimDag
145 * Lot of small cleanups and other bug fixes

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

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

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