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)
+ - 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.
+ - Stop setting random seed with srand() at initialization.
XML
- In <host> and <peer>, 'availability_file' is now 'speed_file'.
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.
-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 xbt_str_join_array().
- Drop cunit, use Catch2 instead.
Kernel:
Fixed bugs:
- #132: Java: a process can not shut down its own host
+ - #220: S4U: detached send causes exception if sender terminates soon after sending
- #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
+ - #324: S4U: Attempting to create an actor on turned off host segfaults instead of throwing
- #325: Turning off a host has different behavior on sleeping actors and computing actors
