SimGrid (3.23) NOT RELEASED (Release Target: June 21. 2019, 15:54 UTC)
General:
- Stop setting random seed with srand48() at initialization.
- Use addr2line as a fallback for stacktraces when backtrace is not available.
- Build option -Denable_documentation is now OFF by default.
+ - Network model 'NS3' was renamed into 'ns-3'.
+ - SunOS and Haiku OS support. Because exotic platforms are fun.
+
+Python:
+ - Simgrid can now hopefully be installed with pip.
+
+S4U:
+ - wait_any can now be used for asynchronous executions too.
XBT:
- New log appenders: stdout and stderr. Use stdout for xbt_help.
- SMPI now reports support of MPI3.1. This does not mean SMPI supports all MPI 3 calls, but it was already the case with 2.2
- MPI/IO is now supported over the Storage API (no files are written or read, storage is simulated). Supported calls are all synchronous ones.
- MPI interface is now const correct for input parameters
+ - MPI_Ireduce, MPI_Iallreduce, MPI_Iscan, MPI_Iexscan, MPI_Ireduce_scatter, MPI_Ireduce_scatter_block support
+ - Fortran bindings for async collectives.
+ - MPI_Comm_get_name, MPI_Comm_set_name, MPI_Count support.
Model-checker:
- Remove option 'model-check/record': Paths are recorded in any cases now.
faster because of cache effects. So there is no need to clutter the
code to allow the user to go for the unefficient mode.
+Network models:
+ - Remove the lagrange-based models (Reno/Reno2/Vegas). The regular
+ models proved to be more accurate than these old experiments.
+
Fixed bugs (FG=FramaGit; GH=GitHub):

+ - FG#8: make python bindings an optional dependency
- FG#10: Can not use MSG_process_set_data from SMPI any more
- FG#11: Auto-restart actors forget their on_exit behavior
- FG#12: -Denable_lto=OFF doesn't disable LTO
- FG#13: Installs unstripped file 'bin/graphicator'
- FG#14: Installs the empty directory 'doc/simgrid/html'
- FG#15: Setting -Denable_python=OFF doesn't disable the search for pybind11
+ - FG#17: Dead link in doc (pls_ns3)

+ - FG#26: Turning off a link should raise NetworkFailureException exceptions
- GH#133: Java: a process can run on a VM even if its host is off
- GH#320: Stacktrace: Avoid the backtrace variant of Boost.Stacktrace?
- GH#326: Valgrind-detected error for join() when energy plugin is activated
- MPI_Alltoallw support
- Partial MPI nonblocking collectives implementation: MPI_Ibcast, MPI_Ibarrier,
MPI_Iallgather, MPI_Iallgatherv, MPI_Ialltoall, MPI_Ialltoallv, MPI_Igather,
- MPI_Igatherv, MPI_Iscatter, MPI_Iscatterv, MPI_Ialltoallw, MPI_Ireduce,
- MPI_Iallreduce, MPI_Iscan, MPI_Iexscan, MPI_Ireduce_scatter,
- MPI_Ireduce_scatter_block, with fortran bindings.
+ MPI_Igatherv, MPI_Iscatter, MPI_Iscatterv, MPI_Ialltoallw.
- MPI_Request_get_status, MPI_Status_set_cancelled, MPI_Status_set_elements
- support, MPI_Comm_get_name, MPI_Comm_set_name
+ support
- Basic implementation of generalized requests (SMPI doesn't
allow MPI_THREAD_MULTIPLE) : MPI_Grequest_complete, MPI_Grequest_start
