SimGrid (3.31.1) NOT RELEASED YET (v3.32 expected June 21. 2022, 09:13 UTC)
-S4U:
- - Added the xbt_enforce macro. This has the same syntax as xbt_assert. The only difference is that an AssertionError
- exception is thrown if the condition is not satisfied, instead of calling abort().
-
Python:
- Added the following bindings / examples:
- Comm (now 100% covers the C++ interface):
- this_actor.parallel_execute
- Exec.suspend
- Exec.wait_for
- - Added an AssertionError exception that may be thrown in case of error. For instance, creating tow hosts with the
- same name will now throw this exception instead of killing the interpreter.
+ - Added an AssertionError exception that may be thrown in case of error.
+ For instance, creating two hosts with the same name will now throw this exception
+ instead of killing the interpreter.
Platform description & visualization:
- - More robust sanity checks for platforms, to reject unallowed topologies with
+ - More robust sanity checks for platforms, to reject forbidden topologies with
a proper error message.
- - One new C++ platform example, supernode.cpp. A Python script (supernode.py)
- demonstrates how we can generate a nice graphical representation of the
- platform.
+ - New platform example: supernode.cpp and supernode.py.
+ The Python version generates a nice graphical representation of the platform.
+ - platform_graph_export_csv() dumps a platform topology to a CSV file.
+ - Bug fixes around fat-tree topologies.
General:
- - SimGrid now requires a compiler with C++17 support.
- - Modified the host_by_name functions:
- - Now, they return only hosts, not VMs, and in a much more efficient way.
- - If one wants to find a VM by name, he now needs to know the host on
- which it runs and call vm_by_name (or manually iterate over the list of hosts)
-
-Tools:
- - Enhancements to the graphicator tool:
- - Allow to dump the platform topology as a CSV file representing the edges
- of the graph (in addition to the DOT format).
- - Fix graphicator for "cluster" topologies (e.g. fat-tree, dragonfly).
+ - SimGrid now requires a compiler with C++17 support to compile the lib.
+ Our public headers still allow the user code to be compiled in C++14.
+ - Support graphviz v3 and ns-3 v3.36 (older versions are still supported).
+
+S4U:
+ - kill signal Comm::on_completion that was not working anyway.
+ - Expose signals Activity::on_suspend and Activity::on_resume
+ - Added the xbt_enforce macro. This has the same syntax as xbt_assert, but
+ an AssertionError exception is thrown if the condition is not satisfied
+ instead of calling abort().
+ - Various cleanups around virtual machines:
+ - host_by_name() and friends now only return hosts. VMs are now excluded.
+ - It is now impossible to search a VM by name globally.
+ You can only search VM by name on a given PM, so either you know
+ the PM on which your VM runs and you can search by name, or you need
+ to manually iterate over all PMs to search this VM.
+ - The s4u::VirtualMachine constructor is now deprecated.
+ Please use s4u::Host::create_vm() instead.
+ - Rename s4u::VirtualMachine::on_creation() to on_vm_creation() to
+ avoid confusion with s4u:Host::on_creation() that is inherited.
+ Also s4u::VirtualMachine::on_destruction -> on_vm_destruction().
+ - One-sided communications (Comm::sendto) can now be detached,
+ and should now be more resilient to network and host faults.
+ - New: s4u::Exec::get_thread_count()
+
+SMPI:
+ - Implement MPI_File_get_type_extent(), MPI_File_s/get_atomicity() and
+ MPI_File_get_byte_offset()
+ - Intercept getpid() calls to return the simulated ones.
+ - Fix various bugs in MPI IO.
+
+Models:
+ - Fix a bug when using ptasks and multicores (FG!111).
+
+Graphicator tool:
+ - Allow to dump the platform topology as a CSV file representing the edges
+ of the graph (in addition to the DOT format).
+ - Fix graphicator for "cluster" topologies (e.g. fat-tree, dragonfly).
+
+Model-Checker:
+ - New: sthread intercepts at runtime on pthread operations, and
+ verify it formally. This code is still a PoC but may even work for you.
+ - Sync MBI generators with upstream changes.
+ - Various cosmetics, small bug fixes and inner refactorings
Fixed bugs (FG#.. -> FramaGit bugs; FG!.. -> FG merge requests)
(FG: issues on Framagit; GH: issues on GitHub)
+ - FG!98: Re-enable the tests for legacy stochastic profiles
- FG#105: "Variable penalty should not be negative!" with in-flight messages and bandwidth profiles
- FG#109: Application time reported by --cfg=smpi/display-timing:yes is wrong
- FG!109: Trigger new engine solve upon host events such as host on/off
- FG#110: Wait_any does not trigger new model solve when host events occur
- FG#111: Wrong execution time in rare cases when using multicore
+ - FG!116: SMPI/replay: Fix issue with recv of size =0
