communication flow.
- Callback signature: double (double capacity, int n_activities): given the
current resource's capacity and number of activities running on it,
- returns the new capacity.
+ returns the new capacity.
- Note that this callback is in the critical path of the system solve and
should not take long to execute.
- Examples:
- Disk: examples/cpp/io-degradation
- - Link: examples/cpp/network-nonlinear
- - CPU: examples/cpp/exec-cpu-nonlinear
+ - Link: examples/cpp/network-nonlinear
+ - CPU: examples/cpp/exec-cpu-nonlinear
+ - Dynamic factors for CPU and disk: similarly to dynamic network factors,
+ allows the user to set a callback which can affect the progress of activities
+ (multiplicative factor applied when updating the amount of work remaining).
+ - Example: examples/cpp/exec-cpu-factors
+
+Python:
+ - Added support to programmatic platform creation in Python.
+ - Several new methods were added to Python interface. For more details, see
+ the corresponding documentation.
+ - New python examples:
+ - Clusters: examples/python/clusters-multicpu
+ - Disk: examples/python/io-degradation
+ - CPU: examples/python/exec-cpu-nonlienar
+ - Link: examples/python/network-nonlinear
S4U:
- New: s4u::Disk::set_sharing_policy() and s4u::Host::set_sharing_policy().
Allows the configuration of non-linear resource sharing for hosts and
disks.
+SMPI:
+ - TI Tracing/Replay:
+ - Multiple fixes to ensure reproducibility of tracing
+ - scan/excan can now be replayed
+ - wait action now uses ranks and not pid, as the other ones.
+ - smpi/init and smpi/finalization-barrier are now valid for replays.
+
Documentation:
* New section "Release Notes" documenting recent and current developments.
+ * New section "Modeling I/O: the realistic way" presenting how to properly
+ model disks in SimGrid.
+ * Improvements in API Reference for C++ and Python interfaces.
+ns-3 model:
+ - Make wifi creation compatible with ns-3 version 3.34 too.
+
+Fixed bugs (FG#.. -> FramaGit bugs; FG!.. -> FG merge requests)
+ (FG: issues on Framagit; GF: issues on GForge; GH: issues on GitHub)
+ - FG#78: Multiple fixes for SMPI replay:
+ - TI tracing of allotallv/w was outputting wrong values
+ - MPI_LOGICAL in fortran is actually 32 bits wide, and not 8.
+ - FG#77: Search feature of doc is broken (update sphinx theme version)
