+
+Java:
+ - Expose host load plugin: loadInit, getCurrentLoad, getComputedFlops, getAvgLoad
+
+Core:
+ - Replace our own code to display a backtrace (that was forking addr2line)
+ with the Boost.Stacktrace library.
+ You won't see your backtraces without this optional dependency.
+
+MSG:
+ - Drop MSG_process_create_from_stdfunc() from the API.
+ This C++ function was a pimple in the C API, made necessary at some
+ point by the Java bindings. This is fixed now.
+
+XBT:
+ - Drop sg_cmdline. Please use xbt_cmdline instead.
+ - Drop the C xbt_os_sem_t; Use the C++ xbt::OsSemaphore.
+ OsSemaphore is implemented in a portable way with C++11 threads.
+ This should allow much more threads to be created at the same time,
+ allowing Mac and Java users to simulate many more actors.
+ - Drop several unused xbt_os_thread_t functions:
+ - xbt_os_thread_get_extra_data()
+ - xbt_os_thread_set_extra_data()
+ - xbt_os_thread_self()
+ - xbt_os_thread_self_name()
+
+Fixed bugs:
+ - #261: Document the parameters of parallel execution's constructor
+ - #314: SMPI args internal cleanup
+ - #316: Fix a bug related to the CPU utilization of multi-core VM

+SimGrid (3.21) October 3. 2018
The Restarting Documentation (TRD) Release.
a git repository to fork as a starting point, and a docker image)
- Started but not finished a SMPI tutorial inspired from the JLPC'14 one.
- The Developper manual is still to be converted (not compiled until then)
+ - Some parts are still missing in this conversion (such as the
+ platform and deployment sections) while others were blindly converted
+ and would need more love (such as the configuration flags).
+ Things will certainly further improve in the future releases.
S4U new features:
- Fully reimplement auto_restart mechanism that was utterly broken
(fix #22, #131 and #281 that were all very related)
+ - Implement semaphores (fix #303 and #291)
- When creating an actor from a function and its parameters,
move-only parameters are not allowed anymore, as it would prevent
the actor to be restartable if its parameters are consumed on run.
- - s4u::Io: IOs go asynchronous as activities. This comes with new methods in the
- s4u::Storage class:
+ - s4u::Io: IOs go asynchronous as activities. New methods in s4u::Storage:
- io_init(sg_size_t, s4u::Io::OpType) to create a READ or WRITE asynchronous
IO operations that can be started, waited for, or canceled as a regular
activity.
- #288: MPI_Init(NULL, NULL)
- #289: Improve documentation of Actor::on_destruction and this_actor::on_exit()
- #290: Method to check if a mailbox has a message ready to be consumed
+ - #291: [s4u] semaphores do not seem available yet
- #294: Alltoall collective implementation of mpich
- #295: Starting a Host as OFF is not supported
- #296: DTD too permissive
