- 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
+ refactoring took almost 10 years to properly complete.
S4U:
- Activity::set_remaining() is not public anymore. Use for example
Comm::set_payload_size() to change the size of the simulated data.
- New function: Engine::flatify_platform(), to get a fully detailed vision of the
configured platform.
+ - Full simDAG integration: Activity::start() actually starts only when all dependencies
+ 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.
Kernel:
- - optimize an internal datastructure, leading to a potentially big
- performance gain (in particular with many detached comms)
+ - optimize an internal datastructure (use a set instead of a list for ongoing activities),
+ 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.
+ - New function SMPI_app_instance_start() to easily start a MPI instance in your S4U simulation.
Models:
- Write the section of the manual about models, at least.
- Same for the latency
- Rewrite the corresponding documentation.
- Allow to disable the TCP windowing modeling by setting network/TCP-gamma to 0.
+ - Finally kill the 'compound' host model. You can change the CPU or network model
+ with the default host model, as it should.
+ - Rename option "surf/precision" to "precision/timing" for clarity.
+ - Rename option "maxmin/precision" to "precision/work-amount" for clarity.
+ - New function: Engine::flatify_platform() to debug your platform.
sthread:
- Implement pthread_join in MC mode.
+ - Implement semaphore functions in sthread.
+ - Add an intricated way to verify the access to non-reentrant data structures
+ It requires code annotation, as shown in examples/sthread/stdobject/stdobject.cpp
+
+Model checking:
+ - 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
+ configuration option.
+ - Stateless model-checking is now usable on any system, including Mac OSX and ARM processors.
+
+XBT:
+ - simgrid::xbt::cmdline and simgrid::xbt::binary_name are gone.
+ Please use simgrid::s4u::Engine::get_cmdline() instead.
Documentation:
- New section in the user guide on the provided performance models.
