SimGrid (3.25.1) UNRELEASED (target: March 20 2020 or v3.26 on 3/26/20)
Important user-visible changes:
+ - SimGrid now requires a compiler with C++14 support.
+ Sibling projects should upgrade their FindSimgrid.cmake
- Surf precision default value is now 1e-9, instead of 1e-5. This was changed as
several users had difficult to understand issues when using high bandwidth or
small latency events. The new value was already the default for SMPI and
Documentation:
- New examples: wifi networks, and communication suspend
+XML and models:
+ - 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.
+
+General:
+ - LTO is now enabled for Intel/clang compilers.
+ - LTO behavior on GCC can be parameterized using LTO_EXTRA_FLAG in cmake.
+ 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.
+
S4U:
- the on_exit() of each actor is also executed when the simulation deadlocks.
- New functions: s4u::Activity:: suspend(), resume() and is_suspended()
- Many MSG tests were converted to the new S4U's interface in C, that
was extended for that.
-General:
- - Require a compiler with C++14 support.
- Take care to upgrade FindSimgrid.cmake if it's used.
- - LTO is now enabled for Intel/clang compilers.
- - LTO behavior on GCC can be parameterized using LTO_EXTRA_FLAG in cmake.
