src/dest, and communicator information). This may change simulation times
for very small message sizes, but should be more realistic.
-Documentation:
- - New examples: wifi networks, and communication suspend
-
-XML and models:
+New features:
- New routing 'WiFi' that makes it easier to specify a wifi network zone.
- - New plugin: wifi_energy. See the associated example.
- - New plugin: link_load. See the associated example.
+ - New plugins: wifi_energy and link_load. See the associated examples.
+ - New examples: wifi networks, and communication suspend.
General:
- LTO is now enabled for Intel/clang compilers.
Setting it to "auto" will use all available cores, while setting it to n will
use n cores to speedup link step (usage: cmake -DLTO_EXTRA_FLAG=4).
- Remove obsolete option --cfg=contexts/parallel-threshold.
+ - Further improve the documentation.
S4U:
- the on_exit() of each actor is also executed when the simulation deadlocks.
C binding and interface:
- The return type of the sg_actor_on_exit() callbacks is now 'void'
(int value was previously ignored)
+ - Many C functions were renamed to follow a common naming style
+ (sg_object_get_something and sg_object_set_something). As usual, the deprecated
+ names are kept until version 3.30.
- Many MSG tests were converted to the new S4U's interface in C, that
was extended for that.

(documenting all internals this way is overkill + doxygen scales badly)
- New tutorial on S4U (highly inspired from the old MSG one, but with
a git repository to fork as a starting point, and a docker image)
- - Started but not finished a SMPI tutorial inspired from the JLPC'14 one.
+ - Started but not finished an SMPI tutorial inspired from the JLPC'14 one.
- The Developper manual is still to be converted (not compiled until then)
- Some parts are still missing in this conversion (such as the
platform and deployment sections) while others were blindly converted
* This is (mainly) a backward compatible change: v4 are valid v4.1 files
- <zone> can be used as a synonym for the now deprecated <as>
- <zoneRoute> can be used as a synonym for the now deprecated <asroute>
- - <bypassZoneRoute> an be used as a synonym for the now deprecated <bypassAsRoute>
+ - <bypassZoneRoute> can be used as a synonym for the now deprecated <bypassAsRoute>
- <actor> can be used as a synonym for the now deprecated <process>
- state_file and avail_file periodicity is now easier to express
(check the documentation) the old behavior should still work.
TRACE:
* Two new tracing options for adding comments to trace file so you
can track your experiments (see --help-tracing for details).
- * New option to generate a impoverished trace file (--cfg=tracing/basic:1)
+ * New option to generate an impoverished trace file (--cfg=tracing/basic:1)
* Adding the SimGrid version that generated the trace file as a comment.
* Instrumenting other MSG functions (MSG_task_isend_with_matching and MSG_task_dsend)
* Fix to avoid key clashes on Paje links
MSG but a few things really had to disappear. The main differences
with the previous version are:
1) no more m_links_t and the corresponding functions. Platforms are
- directly read from a XML description and cannot be hard-coded

anymore. The same format is used for application deployment
description. The new format is described in the documentation.
Have a look in tools/platform_generation. There is a tiny script
