121 The "Desktop Grid needs love too" release (also called "Xmas release").
122 Most important changes:
123 * Big speedup through lazy evaluation of the linear models
124 * Supernovae mode: Compile everything in one unit to improve inlining
125 * Simix network module for internal cleanups
126 * Load DAX of applications into SimDag
127 * Lot of small cleanups and other bug fixes

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

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

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