39 The "OMG! They Killed Kenny!" version. Major changes:
41 * Java and Ruby bindings were removed from the main archive
42 - They are now distributed separately
43 * GRAS is not considered as stable anymore, but experimental. Sorry.
44 * First support for parallel simulation:
45 - Can run the user code of any simulation in parallel.
46 - Basic support for multi-cores hosts in platform files
47 * Improved P2P support:
48 - Peer tag in platform files for DSL connected nodes
49 - Vivaldi routing scheme for lightweigted yet accurate models
50 * Improved SMPI: Faster Fortran, automatic privatization of C globals
51 * Tracing: trace contains the full platform hierarchy
52 exactly as declared using the ASes of the platform file
54 Plus numerous other goodies (check the ChangeLog for details)

113 The "Desktop Grid needs love too" release (also called "Xmas release").
114 Most important changes:
115 * Big speedup through lazy evaluation of the linear models
116 * Supernovae mode: Compile everything in one unit to improve inlining
117 * Simix network module for internal cleanups
118 * Load DAX of applications into SimDag
119 * Lot of small cleanups and other bug fixes

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

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

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