- 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.
+ - Rename Link::get_usage() to Link::get_load() for consistency with Host::
+
+New plugin: Operation
+ - Operations are designed to represent workflows, i.e, graphs of repeatable Activities.
+ - Documentation: https://simgrid.frama.io/simgrid/Plugins.html#operation
+ - Examples: examples/cpp/operation-*
+
+New plugin: Battery
+ - Enable the management of batteries on hosts.
+ - Documentation: https://simgrid.frama.io/simgrid/Plugins.html#battery

+
Kernel:
- 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.
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.
