- Rework the internals, for simpler and modern code. This shall unlock many future improvements.
- You can now define plugins onto SafetyChecker (a simple DFS explorer), using the declared signals.
See CommunicationDeterminism for an example.
- - Support mutex and semaphore in DPOR reduction
+ - Support mutex, semaphore and barrier in DPOR reduction
- Seems to work on Arm64 architectures too.
- Display a nice error message when ptrace is not usable.
+ - New test suite, imported from the MPI Bugs Initiative (MBI). Not all MBI generators are integrated yet.
+ - Remove the ISP test suite: it's not free software, and it's superseeded by MBI.
SMPI:
- fix for FG#100 by ensuring small asynchronous messages never overtake larger
S4U:
- New signal: Engine::on_simulation_start_cb()
+ - Reimplementation of barriers natively.
+ Previously, they were implemented on top of s4u::Mutex and s4u::ConditionVariable.
+ The new version should be faster (and can be used in the model-checker).
+
+MSG:
+ - MSG_barrier_destroy now expects a non-const msg_barrier parameter.
New plugin: the Chaos Monkey (killing actors at any time)
- Along with the new simgrid-monkey script, it tests whether your simulation
