Virtual Machines
- Allow multicore VMs, along with the correct sharing computations
+ Energy
+ - New function to update the consumption of all hosts at once.
+
MSG
- The netzone are now available from the MSG API.
The old names still work, but are now deprecated.
SMPI
- New algorithm to privatize globals: dlopen, with dynamic loading tricks
- New option: smpi/keep-temps to not cleanup temp files
+ - New option : smpi/shared-malloc-blocksize . Relevant only when global shared
+ mallocs mode is used, allows to change the size of the fake file used
+ (default 1MB), to potentially limit the number of mappings for large runs.
- Support for sparse privatized malloc with SMPI_PARTIAL_SHARED_MALLOC()
+ - Fortran ifort and flang compilers support
+ - New RMA calls supported (experimental) :
+ - MPI_Win_allocate, MPI_Win_create_dynamic, MPI_Win_attach
+ - MPI_Win_detach, MPI_Win_set_info, MPI_Win_get_info
+ - MPI_Win_lock_all, MPI_Win_unlock_all, MPI_Win_flush
+ - MPI_Win_flush_local, MPI_Win_flush_all, MPI_Win_flush_local_all
+ - MPI_Op_commutative, MPI_Fetch_and_Op, MPI_Compare_and_swap
+ - MPI_Rput, MPI_Rget, MPI_Raccumulate, MPI_Rget_accumulate
XBT
- Replay: New function xbt_replay_action_get():
