SimGrid (3.31.1) NOT RELEASED YET (v3.32 expected June 21. 2022, 09:13 UTC)
-Python:
- - Added the following bindings / examples:
- - Comm (now 100% covers the C++ interface):
- - Comm.dst_data_size, Comm.mailbox, Comm.sender, Comm.start_time, Comm.finish_time
- - Comm.state_str [examples: examples/python/comm-failure/, examples/python/comm-host2host/]
- - Comm.remaining [examples: examples/python/comm-host2host/, examples/python/comm-suspend/]
- - Comm.set_payload_size [example: examples/python/comm-host2host/]
- - Comm.set_rate [example: examples/python/comm-throttling/]
- - Comm.sendto, Comm.sendto_init, Comm.sendto_async [example: examples/python/comm-host2host/]
- - Comm.start, Comm.suspend, Comm.resume [example: examples/python/comm-host2host/]
- - Comm.test_any [example: examples/python/comm-testany/]
- - Comm.wait_until [example: examples/python/comm-waituntil/]
- - Engine:
- - Engine.host_by_name [example: examples/python/comm-host2host/]
- - Engine.mailbox_by_name_or_create [example: examples/python/comm-pingpong/]
- - Engine.set_config
- - Mailbox: Mailbox.ready [example: examples/python/comm-ready/]
- - Ptask [example: examples/python/exec-ptask/]:
- - this_actor.exec_init
- - this_actor.parallel_execute
- - Exec.suspend
- - Exec.wait_for
- - 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 forbidden topologies with
- a proper error message.
- - 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 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).

+ - Tested with clang (v11, v13, v14 and v16), gcc (v7 to v13) and IntelCC v2022.2
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().
+ - API evolutions:
+ - kill signal Comm::on_completion that was not working anyway.
+ - Expose signals Activity::on_suspend and Activity::on_resume
+ - New macro xbt_enforce(): similar to xbt_assert(), but throws an AssertionError
+ instead of calling abort().
+ - New: s4u::Exec::get_thread_count()
- 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.
- 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.

SMPI:
- Implement MPI_File_get_type_extent(), MPI_File_s/get_atomicity() and
- 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).

+
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.
+ - First bits of sthread, that intercepts pthread operations at runtime.
+ The intend is to use it together with simgrid-mc, but it is TBD.
- Sync MBI generators with upstream changes.
- Various cosmetics, small bug fixes and inner refactorings
