60 - Can run the user code of any simulation in parallel.
61 - Basic support for multi-cores hosts in platform files
62 * Improved P2P support:
63 - Peer tag in platform files for DSL connected nodes
64 - Vivaldi routing scheme for lightweigted yet accurate models
65 * Improved SMPI: Faster Fortran, automatic privatization of C globals
66 * Tracing: trace contains the full platform hierarchy
67 exactly as declared using the ASes of the platform file
69 Plus numerous other goodies (check the ChangeLog for details)

128 The "Desktop Grid needs love too" release (also called "Xmas release").
129 Most important changes:
130 * Big speedup through lazy evaluation of the linear models
131 * Supernovae mode: Compile everything in one unit to improve inlining
132 * Simix network module for internal cleanups
133 * Load DAX of applications into SimDag
134 * Lot of small cleanups and other bug fixes

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

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

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