SimGrid (3.7) NOT RELEASED; urgency=low
- The "Simplicity does not preceed complexity, but follows it" release.
+ The "sprint cleanups (before spring)" release.
Models:
+ * We can specify the smpi latency/bandwidth factor with command line
+ add --cfg=smpi/bw_factor:"threshold0:value0;...;thresholdN:valueN"
+ or add --cfg=smpi/lat_factor:"threshold0:value0;...;thresholdN:valueN"
+ You can also use the "config tag" from platform file by adding this line
+ <prop id="smpi/bw_factor" value="threshold0:value0;...;thresholdN:valueN"></prop>
+ (see "example/platforms/tag_config.xml" to use "config tag").
+ Note that the command line supersedes the platform file configuration.
+ * Change the correction factors used in LMM model, according to
+ the lastest experiments described in INRIA RR-7821.
+ Accuracy should be improved this way.
+ (TODO: this is not true in the code, yet)
* Use the partial invalidation optimization by default for the
network too. Should produce the exact same results, only faster.
* Major cleanup in surf to merge models and split some optimization
* Rename the coordinates configuration option to
network/coordinates, and document it
* Use now crosstraffic keyword instead of the terribly missleading
- fullduplex keyword. Use --cfg=network/crosstraffic:1. This is
- activated by default now in the current default model.
+ fullduplex keyword. It is activated by default now in the current
+ default model, use --cfg=network/crosstraffic:0 to turn it off.
+ * Experimental: new configuration option --cfg=surf/nthreads:N to run
+ analytical models in parallel with N threads (default is 1).
+ * Ongoing refactoring the model parsing to make XML files optional
+ (more work is needed here to fully achieve this goal)
Simix:
* Stabilize the parallel execution mode of user contexts
tasks that are finished and should constitute the return value of
SD_simulate.
+ SMPI:
+ * Enable it by default now that it is considered rather stable.
+
XBT:
* Mallocators: allow value NULL for the reset function.
* Dicts: new function xbt_dict_new_homogeneous(void(*)(void*)) to
