Portability status:
- FreeBSD: Disable SMPI mmap privatization, switch automatically to dlopen.
- Mac, BSD: dlopen+thread broken, switch automatically to raw contexts.
+ - Java JAR file should be finally fully working on Mac OSX too.
XML platforms: Switch to platform v4.1 format.
* This is (mainly) a backward compatible change: v4 are valid v4.1 files
- <zone> can be used as a synonym for the now deprecated <as>
- - <zone
Zoute> an be used as a synonym for the now deprecated <asroute>
+ - <zone
Route> can be used as a synonym for the now deprecated <asroute>
- <bypassZoneRoute> an be used as a synonym for the now deprecated <bypassAsRoute>
- <actor> can be used as a synonym for the now deprecated <process>
- state_file and avail_file periodicity is now easier to express
- Remove attribute 'content_type' of <storage_type>: was never used
- Make attribute 'model' of <storage_type> optional: for future usage
- Remove Bconnection model property: was never (in)validated. Replaced by
- the maximum of the read and write bandwidth as a resource constraint.

SD_simulate_with_update (double how_long, xbt_dynar_t changed_tasks_dynar)
When one wants to get the list of tasks whose states have changed during a
- simulation round, s/he has to allocate and free a dynar and use it as argument
- to this function. The former SD_simulate (double how_long) now returns void.

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 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
+
+ S4U
+ - New: this_actor::isMaestro() returns whether we are in kernel mode.
XBT
- Replay: New function xbt_replay_action_get():
- DROPPED FUNCTION: xbt_str_varsubst()
- DROPPED MODULE: strbuff. We don't need it anymore.
- DROPPED MODULE: matrix. We don't need it anymore.
+ - DROPPED MODULE: lib. We don't need it anymore.
