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

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

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

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

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