+SimGrid (3.34.1) not released (Target: fall 2023)
+
+S4U:
+ - New class ActivitySet to ease wait_any()/test_any()/wait_all()
+ - Deprecate {Comm,Io,Exec}::{wait_any,wait_all,test_any} and friends
+ - New function NetZone::add_route(host1, host2, links) when you don't need gateways
+ Also add a variant with s4u::Link, when you don't want to specify the directions
+ on symmetric routes.
+ - Introduce a Mailbox::get_async() with no payload parameter. You can use the new
+ Comm::get_payload() once the communication is over to retrieve the payload.
+
+SMPI:
+ - New SMPI_app_instance_join(): wait for the completion of a started MPI instance
+ - MPI_UNIVERSE_SIZE now initialized to the total amount of hosts in the platform
+
+Python:
+ - Make the host_load plugin available from Python. See examples/python/plugin-host-load
+ - Mailbox::get_async() does not return a pair anymore. Use comm.get_payload() instead.
+ - Comm::waitall/waitany/testany() are gone. Please use ActivitySet() instead.
+ - Comm::waitallfor() is gone too. Its semantic was unclear on timeout anyway.

+
+C API:
+ - Introduce sg_activity_set_t and deprecate wait_all/wait_any/test_any for
+ Exec, Io and Comm.
+

+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.
+
+General:
+ - SimGrid now requires a compiler with C++17 support for public headers too.
+ Sibling projects should upgrade their FindSimGrid.cmake
+ - Remove the MSG API: its EOL was scheduled for 2020.
+ - Remove the Java bindings: they were limited to the MSG interface.
+ - On Windows, you now need to install WSL2 as the native builds are now disabled.
+ It was not really working anyway.
+ - Support for 32bits architecture is not tested anymore on our CI infrastructure.
+ It may break in the future, but we think that nobody's using SimGrid on 32 bits.
+ - Remove the surf module. It was replaced by the kernel/models module, and that
+ refactoring took almost 10 years to properly complete.
+
+S4U:
+ - Activity::set_remaining() is not public anymore. Use for example
+ Comm::set_payload_size() to change the size of the simulated data.
+ - New function: Engine::flatify_platform(), to get a fully detailed vision of the
+ configured platform.
+ - 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::
+ - Every signal now come with a static version that is invoked for every object of that class,
+ and an instance version that is invoked for this specific object only. For example,
+ s4u::Actor::on_suspend_cb() adds a callback that is invoked for the suspend of any actor while
+ s4u::Actor::on_this_suspend_cb() adds a callback for this specific actor only.
+ - Activity::on_suspended_cb() is renamed to Activity::on_suspend_cb(), and fired right before the suspend.
+ - Activity::on_resumed_cb() is renamed to Activity::on_resume_cb(), and fired right before the resume.
+ - Resource::on_state_change_cb() is renamed to Resource::on_onoff_cb() to distinguish from the
+ Activity::on_state_change_cb() that is related to the activity state machine, not on/off.
+ - Activity signals (veto, suspend, resume, completion) are now specialized by activity class.
+ That is, callbacks registered in Exec::on_suspend_cb will not be fired for Comms nor Ios.
+
+New S4U plugins:
+ - Battery: Enable the management of batteries on hosts.
+ See the examples under examples/cpp/battery-* and the documentation in the Plugins page.
+ - Photovoltaic: Enable the management of photovoltaic panels on hosts.
+ See the examples under examples/cpp/photovoltaic-* and the documentation in the Plugins page.
+
+Kernel:
+ - 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.
+
+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.
+ - 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
+ - See also "A Flow-Level Wi-Fi Model for Large Scale Network Simulation"
+ https://hal.archives-ouvertes.fr/hal-03777726
+ - Merge parameters network/bandwidth-factor and smpi/bw-factor that serve the same purpose.
+ - Same for the latency
+ - Rewrite the corresponding documentation.
+ - Allow to disable the TCP windowing modeling by setting network/TCP-gamma to 0.
+ - Finally kill the 'compound' host model. You can change the CPU or network model
+ with the default host model, as it should.
+ - Rename option "surf/precision" to "precision/timing" for clarity.
+ - Rename option "maxmin/precision" to "precision/work-amount" for clarity.
+ - New function: Engine::flatify_platform() to debug your platform.
+
+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:
+ - 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 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 backtraces when replaying a MC trace (with model-check/replay)
+ and the status of all actors on deadlocks in MC mode.
+
+XBT:
+ - simgrid::xbt::cmdline and simgrid::xbt::binary_name are gone.
+ Please use simgrid::s4u::Engine::get_cmdline() instead.
+
+Documentation:
+ - New tutorial on simulating DAGs.
+ - New section in the user guide on the provided performance models.
+ - New section presenting some technical good practices for (potential) contributors.
+ - Add a section on errors and exceptions to the API documentation.
+ - Move the s4u examples to a section on their own to ease navigation.
+
+Fixed bugs (FG#.. -> FramaGit bugs; FG!.. -> FG merge requests)
+ (FG: issues on Framagit; GH: issues on GitHub)
+ - FG#18: Java bindings should be redone or removed
+ - FG!118: Wi-Fi callback mechanism
+ - FG!119: SMPI: add option to inject a barrier before every collective call
+ - GH#383: Segfault when adding a disk after load_platform(xml)
+
+----------------------------------------------------------------------------
+
+SimGrid (3.32) October 3. 2022.
+
+The Wiedervereinigung release. Germany was reunited 32 years ago.
+
+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:
+ - 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.
+ 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().
+ - Bug fixes:
+ - One-sided communications (Comm::sendto) can now be detached,
+ and should now be more resilient to network and host faults.
+
+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.
+
+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.
+
+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.
+ - Bug fixes around fat-tree topologies.
+ - Allow to dump the platform topology as a CSV file representing the graph edges
+ with platform_graph_export_csv() (similar to the DOT export).
+ - Fix graphicator for "cluster" topologies (e.g. fat-tree, dragonfly).
+
+Models:
+ - Fix a bug when using ptasks with multicores (FG!111).
+
+Model-Checker:
+ - 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
+
+Fixed bugs (FG#.. -> FramaGit bugs; FG!.. -> FG merge requests)
+ (FG: issues on Framagit; GH: issues on GitHub)
+ - 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#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!98: Re-enable the tests for legacy stochastic profiles
+ - FG!109: Trigger new engine solve upon host events such as host on/off
+ - FG!116: SMPI/replay: Fix issue with recv of size =0
+

-SimGrid (3.29.1) NOT RELEASED YET (v3.30 expected December 21. 2021, 15:59 UTC)
+SimGrid (3.31) March 22. 2022.
+
+The ненасильство release. We stand against war.
+
+Against the agression by a sick system that forces peoples to take arms against each other.
+
+MC:
+ - Rework the internals, for simpler and modern code. This shall unlock many future improvements.
+ - You can now define plugins onto the DFS explorer (previously called SafetyChecker), using the
+ declared signals. See CommunicationDeterminism for an example.
+ - Support mutex, semaphore and barrier in DPOR reduction
+ - Seems to work on Arm64 architectures too.
+ - Display a nice error message when ptrace is not usable.
+ - New test suite, imported from the MPI Bugs Initiative (MBI). Not all MBI generators are integrated yet.
+ - Remove the ISP test suite: it's not free software, and it's superseeded by MBI.
+
+SMPI:
+ - fix for FG#100 by ensuring small asynchronous messages never overtake larger
+ ones, conforming to the standard.
+ - replay: fix waitall behaviour to avoid forgetting requests and leaking
+ their handles.
+ - tracing: ensure that we dump the TI traces continuously during execution and
+ not just at the end, reducing memory cost and performance hit.
+ - Update OpenMPI collectives selection logic to match current one (4.1.2)
+ - Add a coherence check for collective operation order and root/MPI_Op
+ coherence. Potentially costly so not activated unless smpi:pendantic is set
+ or -analyze is given.
+
+S4U:
+ - New signal: Engine::on_simulation_start_cb()
+ - Introduce a new execution mode with this_actor::thread_execute(). This simulate
+ the execution of a certain amount of flops by multiple threads ran by a host. Each
+ thread executes the same number of flops, given as argument. An example of this new
+ function can be found in examples/cpp/exec-threads.
+ - Reimplementation of barriers natively.
+ Previously, they were implemented on top of s4u::Mutex and s4u::ConditionVariable.
+ The new version should be faster (and can be used in the model-checker).
+ - Actor::get_restart_count(): Returns the number of reboots that this actor did.
+
+MSG:
+ - MSG_barrier_destroy now expects a non-const msg_barrier parameter.
+
+New plugin: the Chaos Monkey (killing actors at any time)
+ - Along with the new simgrid-monkey script, it tests whether your simulation
+ resists resource failures at any possible timestamp in your simulation.
+ - It is mostly intended to test the SimGrid core in extreme conditions,
+ but some users may find it interesting too.
+
+Models:
+ - New solver for parallel task: BMF.
+ - More realistic sharing of heterogeneous resources compared to the fair
+ bottleneck solver used by ptask_L07.
+ - Implement the BMF (Bottleneck max fairness) fairness.
+ - Improved resource sharing for parallel tasks with sub-flows (parallel
+ communications between same source and destination inside the ptask).
+ - Parameters:
+ - "--cfg=host/model:ptask_L07 --cfg=host/solver:bmf": enable the ptask
+ model with BMF solver.
+ - "--cfg=bmf/max-iterations: <N>": maximum number of iterations performed
+ by BMF solver (default: 1000).
+ - "--cfg=bmf/precision: <N>": numerical precision used when computing
+ resource sharing (default: 1e-12).
+ - This model requires Eigen3 library. Make sure Eigen3 is installed to use BMF.
+
+General:
+ - Modifications of the Profile mechanism, with some impact on users
+ - Addition of a new (S4U) method to init profiles from generic functions to improve versatility
+ - Fix initial behaviour of state_profiles
+ - Modify periodicity to behave like a period, and not like a loop delay
+
+XBT:
+ - Drop xbt_dynar_shrink().
+
+Python:
+ - Made the following bindings static (previously member functions):
+ - Actor: Actor.kill_all(), Actor.by_pid()
+ - Host: Host.by_name(), Host.current(), Host.on_creation_cb()
+ - Mailbox: Mailbox.by_name()
+ - Added the following bindings:
+ - this_actor.warning()
+ - Mailbox.put_init() [example: examples/python/comm-waitallfor/]
+ - Comm.detach() [example: examples/python/comm-waitallfor/]
+ - Comm.wait_for() [example: examples/python/comm-waitfor/]
+ - Comm.wait_any_for()
+ - Comm.wait_all_for() [example: examples/python/comm-waitallfor/]
+ - Mutex [example: examples/python/synchro-mutex/]
+ - Barrier [example: examples/python/synchro-barrier/]
+ - Semaphore [example: examples/python/synchro-semaphore/]
+
+Build System:
+ - Remove target "make uninstall" which was incomplete and no longer maintained.
+
+Fixed bugs (FG#.. -> FramaGit bugs; FG!.. -> FG merge requests)
+ (FG: issues on Framagit; GH: issues on GitHub)
+ - FG#57: Mc SimGrid should test whether ptrace is usable
+ - FG#87: Smpi scripts fail with spaces in paths
+ - FG#100: [SMPI] Order of the message matching is not guaranteed
+ - FG#101: LGPL 2.1 is deprecated license
+ - FG#104: "make uninstall" not up-to-date
+ - GH#151: Missing mutexes for DPOR.

+
+SimGrid (3.30) January 30. 2022.
+
+The Sunday Bloody Sunday release.
Main user-visible changes:
- - The SimDag API for the simulation of the scheduling of Directed Acyclic
- Graphs has been dropped. It was marked as deprecated for a couple of years.
- We finally complete the implementation of what has been called SimDag++
- internally, i.e., porting the different features of SimDag on top of S4U.
- The new way to simulate the execution of dependent activities directly by
- maestro (without any other actor) is details in the examples/cpp/dag-* series
- of examples.
- - The removal of SimDag led us to also remove the export to Jedule files that
- was tightly coupled to SimDag. The instrumentation of DAG simulation is still
- possible through the regular instrumentation API based on the Paje format.

+ - We also dropped the old and clumsy Lua bindings to create platforms in a
+ programmatic way. It can be done in C++ in a much cleaner way now, which
+ motivates this suppression.
+
S4U:
+ - Introduce on_X_cb() functions for all signals, to attach a new
+ callback to the signal X. The signal variables are now hidden and
+ only these functions should be used.
+ Rationale: this enables the usual deprecation scheme where functions
+ remain for 4 releases if we need to modify the signals, while the
+ current code with the signal variables directly visible prevents any
+ smooth transition.
- New function: Engine::run_until(date), to split the simulation.
- New signal: Activity::on_veto, to detect when an activity fails to start.
+ - Signal change: Comm::on_start(Comm&, bool) has been replaced by
+ Comm::on_send and Comm::recv. These two signals respectively correspond to
+ when the sending or receiving side of a Comm is ready. They are raised at
+ the same locations as the former Comm::on_start signal.
- New function: Engine::track_vetoed_activities() to interrupt run()
when an activity fails to start, and to keep track of such activities.
Please see the corresponding example for more info.

+ - New functions: s4u::Comm::{sendto_init, set_source, set_destination} to enable
+ the use of vetoers with direct host-to-host communications. Both source and
+ destination have to set for a comm to start. Each call to these setters check
+ if all vetoes are satisfied. When it is the case, the comm starts. A use case of
+ these functions is given in examples/cpp/dag-scheduling.
+ - New functions: {Exec, Io}::update_priority allow you to modify the priority of
+ these kinds of activities during their execution. Behavior is detailed in
+ examples/cpp/io-priority/.
SMPI:
- Dynamic costs for MPI operations: New API to allow users to dynamically
- change injected costs for MPI_Recv, MPI_Send and MPI_Isend operations.
- Alternative for smpi/or, smpi/os and smpi/ois configuration options.

+ pointee. Untyped function is deprecated. Use get_data<void>() if you still
+ want to retrieve void*.
Documentation:
- New section: "SimGrid MPI calibration of a Grid5000 cluster"
contexts revealed unstable, specially starting with pybind11 v2.8.0.
