SimGrid (3.32.1) not released yet (target december 22)
General:
+ - SimGrid now requires a compiler with C++17 support for public headers too.
+ Sibling projects should upgrade their FindSimGrid.cmake
- Remove the MSG API: its EOL was scheduled for 2020.
- Remove the Java bindings: they were limited to the MSG interface.
- On Windows, you now need to install WSL2 as the native builds are now disabled.
It was not really working anyway.
- Support for 32bits architecture is not tested anymore on our CI infrastructure.
It may break in the future, but we think that nobody's using SimGrid on 32 bits.
- - Remove the surf module. It was replaced by the kernel/models module, and that
+ - Remove the surf module. It was replaced by the kernel/models module, and that
refactoring took almost 10 years to properly complete.
S4U:
are fullfiled. If it cannot be started right away, it will start as soon as it becomes
possible.
- Allow to set a concurrency limit on disks and hosts, as it was already the case for links.
+ - Rename Link::get_usage() to Link::get_load() for consistency with Host::
+ - Every signal now come with a static version that is invoked for every object of that class,
+ and an instance version that is invoked for this specific object only. For example,
+ s4u::Actor::on_suspend_cb() adds a callback that is invoked for the suspend of any actor while
+ s4u::Actor::on_this_suspend_cb() adds a callback for this specific actor only.
+ - Activity::on_suspended_cb() is renamed to Activity::on_suspend_cb(), and fired right before the suspend.
+ - Activity::on_resumed_cb() is renamed to Activity::on_resume_cb(), and fired right before the resume.
+
+New S4U plugins:
+ - Operation: They are designed to represent workflows, i.e, graphs of repeatable Activities.
+ See the examples under examples/cpp/operation-* and the documentation in the Plugins page.
+ - Battery: Enable the management of batteries on hosts.
+ See the examples under examples/cpp/battery-* and the documentation in the Plugins page.
Kernel:
- optimize an internal datastructure (use a set instead of a list for ongoing activities),
- Synchronize the MBI tests with upstream.
- Show the full actor bactraces when replaying a MC trace (with model-check/replay)
and the status of all actors on deadlocks in MC mode.
- - The safety/stateless aspects of the MC are now enabled by default in all simgrid builds.
- Liveness and stateful aspects are still controled by the enabling_model-checking
+ - The safety/stateless aspects of the MC are now enabled by default in all simgrid builds.
+ Liveness and stateful aspects are still controled by the enabling_model-checking
configuration option.
- Stateless model-checking is now usable on any system, including Mac OSX and ARM processors.
Important user-visible changes:
- SimGrid now requires a compiler with C++14 support.
- Sibling projects should upgrade their FindSimgrid.cmake
+ 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 difficulties to understand issues when using high bandwidth or
small latency events. The new value was already the default for SMPI and
