+SimGrid (3.34) June 26. 2023
Save the planet, skip a release: 3.33 was due 6 months ago, so skip directly to 3.34.
- New Task abstraction: They are designed to represent dataflows, i.e, graphs of repeatable Activities.
See the examples under examples/cpp/task-* and the associated documentation.
- Full simDAG integration: Activity::start() actually starts only when all dependencies

+ are fulfilled. 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::

Kernel:
- - optimize an internal datastructure (use a set instead of a list for ongoing activities),
+ - optimize an internal data structure (use a set instead of a list for ongoing activities),
leading to a potentially big performance gain, in particular with many detached comms.

Models:
- Write the section of the manual about models, at least.
- - WiFi: the total capacity of a link depends on the amout of flows on that link.
+ - WiFi: the total capacity of a link depends on the amount of flows on that link.
- Use the nonlinear callback feature of LMM to reflect this.
- Calibration values can be changed to match different MCS configurations
- See the example teshsuite/models/wifi_usage_decay/wifi_usage_decay.cpp
Model checking:
- Stateless model-checking is now usable on any system, including Mac OSX and ARM processors.
- The 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
+ Liveness and stateful aspects are still controlled by the enabling_model-checking
configuration option.
- Introducing ODPOR and SDPOR reduction strategies
- Introducing guiding heuristics, trying to find bugs faster than DFS in reduced state space.
- Synchronize the MBI tests with upstream.
- - Show the full actor bactraces when replaying a MC trace (with model-check/replay)
+ - Show the full actor backtraces when replaying a MC trace (with model-check/replay)
and the status of all actors on deadlocks in MC mode.
