+SimGrid (3.22) April 1. 2019
+
+The Easter Chrismas Release (this one is somewhat late).
Python:
- We are excited to introduce the SimGrid/S4U interface to your neighborhood
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'.
The implementation was ways too messy to actually work, I guess.
SMPI:
- - Change the way SMPI_SAMPLE_* macros work to avoid invalidating cache
+ - Change the way SMPI_SAMPLE_* macros work to avoid invalidating cache
too often and provide more accurate timings.
+ - Add -gdb, -lldb, and -vgdb shortcuts to help debug MPI codes with smpirun
+ - 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_Request_get_status, MPI_Status_set_cancelled, MPI_Status_set_elements
+ support, MPI_Comm_get_name, MPI_Comm_set_name
+ - Basic implementation of generalized requests (SMPI doesn't
+ allow MPI_THREAD_MULTIPLE) : MPI_Grequest_complete, MPI_Grequest_start
XBT:
- Drop sg_cmdline. Please use xbt_cmdline instead.
-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
