67 - Can run the user code of any simulation in parallel.
68 - Basic support for multi-cores hosts in platform files
69 * Improved P2P support:
70 - Peer tag in platform files for DSL connected nodes
71 - Vivaldi routing scheme for lightweigted yet accurate models

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

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

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

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