SimGrid (3.22) NOT RELEASED (Release Target: December 21. 2018, 22:23 UTC)
Java:
+ - Process termination which was broken at version 3.21 has been repaired.
- Expose host load plugin: loadInit, getCurrentLoad, getComputedFlops, getAvgLoad
+ - Hide the examples into examples/deprecated. New users should use Python.
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.
+ - Bump cmake dependency to 3.5 (provided by Ubuntu 16.04).
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.
+ - Hide the examples into examples/deprecated. New users should use S4U.
+
+XBT:
+ - Drop sg_cmdline. Please use xbt_cmdline instead.
+ - Drop the C xbt_os_mutex_t; Use the C++11 std::mutex.
+ - 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.
+ - Implement the 'thread' factory with std::thread instead of xbt ones.
+ It is not possible to set the stack size with threads anymore, but
+ -fsplit-stack is the way to go nowadays when using threads.
+ - Drop the xbt_os_thread_t module (now unused)
+ - Drop xbt_ex_display(), use simgrid::xbt::log_exception() instead.
+ - Drop cunit, use Catch2 instead.
Fixed bugs:
- #261: Document the parameters of parallel execution's constructor
+ - #300: [s4u] BarrierPtr is missing
+ - #314: SMPI args internal cleanup
+ - #316: Fix a bug related to the CPU utilization of multi-core VM
+ - #318: Invalid trace file when using option --cfg=tracing/smpi/display-sizes:yes
----------------------------------------------------------------------------
- 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).
+ and would need more love (such as the configuration flags).
Things will certainly further improve in the future releases.
S4U new features:
- 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.
- - read_async(sg_size_t) and write_async(sg_size_t) which are wrappers on
+ - read_async(sg_size_t) and write_async(sg_size_t) which are wrappers on
io_init() + start()
Tracing:
We hope to fix it in a future release, and we are sorry for the inconvenience.
Fixed bugs:
- - #22: Process autorestart seem to only work with CAS01 cpus
+ - #22: Process autorestart seem to only work with CAS01 cpus
- #56: Feature request: dynamic SMPI replay
- #93: simgrid should not eat --help
- #111: How to change the loopback link characteristics?
