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.
+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 a bit in the future (please
+ report any glitches), but it seems rather fast and reliable already.
+ - Forget about Java now (and soon about C++)
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.
+
+XML
+ - In <host> and <peer>, 'availability_file' is now 'speed_file'.
+ XML file version remains 4.2 since old files are still compatible.

+Java:

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.
+ - MSG_process_create and MSG_process_attach now crash if the host used
+ to run this process is off.
+ - Fix the protype of MSG_process_on_exit()
+ 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 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.
+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
- #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
+ - #325: Turning off a host has different behavior on sleeping actors and computing actors
