6 The "Winter in Frejus" release. Also known as "ANR/ADT funding helps"
9 * New feature: Model check any simgrid simulation
10 * SMPI: now considered stable
12 - now covers the whole framework
13 - major usability improvements
15 - scalable platform management through hiearchical description
16 - new efficient way to bypass the XML parser
17 * MSG: at last asynchronous functions are available
18 * SIMDAG: many usability improvements (dotloader, ...)
19 * GRAS: finally catch up with latest internal evolutions

55 The "Desktop Grid needs love too" release (also called "Xmas release").
56 Most important changes:
57 * Big speedup through lazy evaluation of the linear models
58 * Supernovae mode: Compile everything in one unit to improve inlining
59 * Simix network module for internal cleanups
60 * Load DAX of applications into SimDag
61 * Lot of small cleanups and other bug fixes

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

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

125 At least, after 2 years of hard work, we managed to release the 3.3
126 version of the SimGrid framework. There is so many changes that the
127 changelog only lists the most important ones, leaving alone the small
128 improvements, bug fixing and new gadgets.
132 * New simulation models, and improvement of the GTNetS wrapper
134 * Large memory savings (mainly in parser)
135 * Faster (twice faster is not uncommon, and from 20 hours to 2
136 minutes on very large scenarios)
137 * Much better scalability (tested up to 250,000 processes)
139 * Complete regression testing framework so that you can trust the tool
140 * Lot of neat new modules in the XBT toolbox
142 This version was throughfully tested on linux 32bits and 64bits
143 (debian), as well as Mac OSX (leopard).
145 Unfortunately, our windows-guy left, and we cannot release the windows
146 version at the same time than the other archs. Any help would be
147 really welcomed here.
149 Some of the 96 included test suites are known to fail, but everything
150 should work anyway (don't panic):
151 * The amok module does not work in real deployment ATM, but I don't
152 see this as release critical since I'm not aware of anyone needing
154 * Some tests about the ability of GRAS to receive messages from
155 exotic platforms fail because I've lost access to these platforms
157 * the example/gras/pmm sometimes fails (about 1/10 of cases). I'm
158 quite puzzled, but I suspect a bug in the test, not in the lib.
159 * the tesh auto-tests "fail" on Mac OSX. This is because "rm -rf" is
160 sometimes too verbose (when the OS creates hidden files, I
161 suspect), but tesh definitly work as the rest on this arch.
163 We hope to manage to do more timely releases in the future, even if
164 that may turn out difficult since big stuff is comming (I don't say
165 much here for the suspense ;)
167 We hope you'll enjoy this new version, and please report any feedback
168 on the <simgrid-user@lists.gforge.inria.fr> list.
