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

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

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

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

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