SimGrid (3.22) NOT RELEASED (Release Target: December 21. 2018, 22:23 UTC)
+The Sneaky Release.
+
+Python:
+ - We are excited to introduce the SimGrid/S4U interface to your neighborhood
+ - Not complete yet: asynchronous activities (amongst others) are still missing
+ - Still ongoing: the interface may change in the future. We need more
+ testers! Please report any glitches.
+ - No new project using Java should start now. Please switch to Python.
+
+General:
+ - Some of the internal cleanups may lead to speed improvements:
+ - The hard limitation on the amount of simulated actors with
+ Java+Mac was removed. Now, the available memory is the only limit.
+ - Our refcounting was tidyied, leading to 10% speedups in some cases.
+ - We are still working on making our code robust to the actor kills
+ and hosts' churn. Things are improving, but it's not perfect yet.
+ - Replaced 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).
+ - Stop setting random seed with srand() at initialization.
+
+XML
+ - In <host> and <peer>, 'availability_file' is now 'speed_file'.
+ XML file version remains 4.2 since old files are still compatible.
+
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).
- - Stop setting random seed with srand() at initialization.
-
MSG:
- Drop MSG_process_create_from_stdfunc() from the API.
This C++ function was a pimple in the C API, made necessary at some
Now use (int,void*) callbacks instead of (void*,void*) ones.
The implementation was ways too messy to actually work, I guess.
+SMPI:
+ - Change the way SMPI_SAMPLE_* macros work to avoid invalidating cache
+ too often and provide more accurate timings.
+
XBT:
- Drop sg_cmdline. Please use xbt_cmdline instead.
- Drop the C xbt_os_mutex_t; Use the C++11 std::mutex.
- Drop xbt_ex_display(), use simgrid::xbt::log_exception() instead.
- Drop cunit, use Catch2 instead.
-XML
- - In <host> and <peer>, availability_file is now speed_file.
- XML file version remains 4.2 since old files are still compatible.
-
-Internal:
+Kernel:
- Many cleanups in the kernel::activity namespace. This was long
overdue, and shall open the path to many future endeavors.
Fixed bugs:
- - #132: Java : a process can not shut down its own host
+ - #132: Java: a process can not shut down its own host
- #261: Document the parameters of parallel execution's constructor
- #300: [s4u] BarrierPtr is missing
- #314: SMPI args internal cleanup
