+SMPI:
+ - Handle leak checking (experimental): SMPI will now display a message if MPI
+ handles are still present at the end of a simulation. This may be nothing,
+ but if the number is high it could be a problem. To display more information
+ about the type of leaked handle, option --cfg=smpi/list-leaks:n. will display
+ the n first leaked pointers and their types. Known issue: MPI_Cancel usage
+ may trigger handle leaks in SMPI.
+ Using smpirun with -wrapper "valgrind --leak-check=full --track-origins=yes"
+ can provide more information to help locate precisely the leaks.
+ - Memory allocations analysis (experimental): MPI codes using malloc/calloc to
+ allocate memory, and not compiled with SMPI_NO_OVERRIDE_MALLOC, can use
+ smpi/display-analysis option to show at the end of execution the amount of
+ memory allocated through these calls, and locate the most expensive one.
+ This helps finding the targets for manual memory sharing, or the threshold
+ to use for smpi/auto-shared-malloc-thresh option.
+ - New implemented MPI calls: MPI_File_set_size, MPI_Aint_add, MPI_Aint_diff,
+ MPI_Type_get_extent_x, MPI_Type_get_true_extent_x, MPI_Status_set_elements_x
+ - Support for MPI C++ datatypes (MPI_CXX_BOOL, MPI_CXX_FLOAT_COMPLEX,
+ MPI_CXX_DOUBLE_COMPLEX, MPI_CXX_LONG_DOUBLE_COMPLEX)
+ - Misc fixes:
+ - better handling of MPI_PROC_NULL
+ - MPI_Group_incl was broken in some cases
+ - PAPI tracing was fixed
+ - MPI_Errhandlers are properly handled for MPI_COMM_WORLD
+ - SMPI will now fail properly when receive size < sent size, instead of
+ just setting MPI_ERR_TRUNCATE and keep going.
+ - Proxy Apps ( https://framagit.org/simgrid/SMPI-proxy-apps ):
+ - Remove useless build patches and split build/run patches on the page
+ - Build in parallel when possible
+ - Test on yum-based systems
+ - New nightly tested Proxy-apps:
+ - OpenMPI mpi-test-suite
+ - Coral MCB, LSMS, Qbox
+ - ECP/Mantevo Cloverleaf3D
