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() + - Drop xbt_ex_display(), use simgrid::xbt::log_exception() instead. + +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. + +Documentation: + - Convert the user manual to Sphinx for improved usability. + Unstable version now hosted on https://simgrid.frama.io/simgrid + Many glitches remain; stay tuned. + - Restrict the Doxygen reference API to the installed header files. + (documenting all internals this way is overkill + doxygen scales badly) + - New tutorial on S4U (highly inspired from the old MSG one, but with + 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.
