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:
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.
+ - Resource::on_state_change_cb() is renamed to Resource::on_onoff_cb() to distinguish from the
+ Activity::on_state_change_cb() that is related to the activity state machine, not on/off.
+ - Activity signals (veto, suspend, resume, completion) are now specialized by activity class.
+ That is, callbacks registered in Exec::on_suspend_cb will not be fired for Comms nor Ios.
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.
+ - Task: They are designed to represent dataflows, i.e, graphs of repeatable Activities.
+ See the examples under examples/cpp/task-* 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.
+ - Photovoltaic: Enable the management of photovoltaic panels on hosts.
+ See the examples under examples/cpp/photovoltaic-* 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
