-SimGrid (3.31.1) NOT RELEASED YET (v3.32 expected June 21. 2022, 09:13 UTC)
+SimGrid (3.32.1) not released yet (target december 22)
+
+General:
+ - On Windows, you now need to install WSL2 as the native builds are now disabled.
+ It was not really working anyway.
+
+S4U:
+ - Activity::set_remaining() is not public anymore. Use for example
+ Comm::set_payload_size() to change the size of the simulated data.
+
+Kernel:
+ - optimize an internal datastructure, leading to a potentially big
+ performance gain (in particular with many detached comms)
+
+MPI:
+ - New option smpi/barrier-collectives to add a barrier to some collectives
+ to detect dangerous code that /may/ work on some MPI implems.
+
+Models:
+ - Write the section of the manual about models, at least.
+ - WiFi: the total capacity of a link depends on the amout of flows on that link.
+ - Use the nonlinear callback feature of LMM to reflect this.
+ - Calibration values can be changed to match different MCS configurations
+ - See the example teshsuite/models/wifi_usage_decay/wifi_usage_decay.cpp
+ - See also "A Flow-Level Wi-Fi Model for Large Scale Network Simulation"
+ https://hal.archives-ouvertes.fr/hal-03777726
+ - Merge parameters network/bandwidth-factor and smpi/bw-factor that serve the same purpose.
+ - Same for the latency
+ - Rewrite the corresponding documentation.
+
+sthread:
+ - Implement pthread_join in MC mode.
+
+Fixed bugs (FG#.. -> FramaGit bugs; FG!.. -> FG merge requests)
+ (FG: issues on Framagit; GH: issues on GitHub)
+ - FG!118: Wi-Fi callback mechanism
+ - FG!119: SMPI: add option to inject a barrier before every collective call, to allow...

+SimGrid (3.32) October 3. 2022.
+
+The Wiedervereinigung release. Germany was reunited 32 years ago.
General:
- SimGrid now requires a compiler with C++17 support to compile the lib.
- Tested with clang (v11, v13, v14 and v16), gcc (v7 to v13) and IntelCC v2022.2
S4U:
- - API evolutions:
+ - API evolutions:
- kill signal Comm::on_completion that was not working anyway.
- Expose signals Activity::on_suspend and Activity::on_resume
- - New macro xbt_enforce(): similar to xbt_assert(), but throws an AssertionError
+ - New macro xbt_enforce(): similar to xbt_assert(), but throws an AssertionError
instead of calling abort().
- New: s4u::Exec::get_thread_count()
- Various cleanups around virtual machines:
Fixed bugs (FG#.. -> FramaGit bugs; FG!.. -> FG merge requests)
(FG: issues on Framagit; GH: issues on GitHub)
- - FG!98: Re-enable the tests for legacy stochastic profiles
- FG#105: "Variable penalty should not be negative!" with in-flight messages and bandwidth profiles
- FG#109: Application time reported by --cfg=smpi/display-timing:yes is wrong
- - FG!109: Trigger new engine solve upon host events such as host on/off
- FG#110: Wait_any does not trigger new model solve when host events occur
- FG#111: Wrong execution time in rare cases when using multicore
+ - FG!98: Re-enable the tests for legacy stochastic profiles
+ - FG!109: Trigger new engine solve upon host events such as host on/off
- FG!116: SMPI/replay: Fix issue with recv of size =0
