-SimGrid (3.19) NOT RELEASED YET (target: March 20 2018, 16:15:27 UTC)
+SimGrid (3.19) Released March 20 2018
- MSG
- - Fix MSG_task_get_remaining_work_ratio() to return 1.0 for tasks that have
- not started.
- - Remove parameter of MSG_process_killall().
- Resetting the PID was bogus anyway (several actors could have the same PID).
+ The Moscovitly-cold Spring release.
+
+ SMPI user-visible improvements:
+ - Support of MPI_Type_create_subarray
+ - Unimplemented MPI calls now abort (instead of issuing a warning)
+ Some harmless calls around errhandlers still only issue a warning.
+ - MPI_Sendrecv was behaving badly when MPI_PROC_NULL was sender or receiver.
+ - Starting MPI ranks (or even MSG/S4U actors) once the simulation started
+ is now possible (mmap privatization was refactored to this end).
+ Adding new SMPI instances should also be technically doable now.
+
+ SMPI internal cleanups:
+ - Removed index notion from SMPI -- no more "getPid() - 1"!
+ In tracing files, actors are called rank-<PROCESS-ID> but these are
+ NOT the real ranks (tracing several communicators is not supported yet).
+ - Deprecate smpi_process_index() (will be removed in 3.22)
+ - Better testing on classical proxy apps, through an external project:
+ https://github.com/simgrid/SMPI-proxy-apps/
Documentation
- Use a graphical TOC to make it easier to find the documentation you need
- Revamp the MSG tutorial
+ MSG
+ - Fix MSG_task_get_remaining_work_ratio(): return 1.0 for unstarted tasks.
+ - Remove parameter of MSG_process_killall().
+ Resetting the PID was bogus anyway (several actors could have the same PID).

S4U
- - Execution->setHost() can be called after start() to migrate it.
+ - Execution->setHost() can be called after start(), to migrate it.
- Comm::test_any() is now implemented.
- s4u::Actor now has onCreation() and onDestruction() signals.
- Install some kernel header files for the users' plugins and more.
include/simgrid/kernel/resource/{Action,Resource,Model}.hpp
include/simgrid/kernel/routing/*Zone.hpp
- XBT
- - Remove XBT_LOG_CONNECT, it should be useless nowadays.
-
SimDag
- SD_task_dependency_add(): remove unused parameters 'name' and 'data'.
- SMPI
- - The privatization of global variables via mmap() is now significantly more
- flexible and allows the use of daemons with SMPI and to add new processes
- while the simulation is running. (Adding new SMPI instances after the
- simulation has already started should also be technically doable now.)
- - Removed index notion from SMPI -- no more "getPid() - 1"!
- This also means that the trace files
- now contain actors called rank-<PROCESS-ID>. These are NOT the real
- ranks, because tracing several communicators right now is not supported.
- - Because of this, smpi_process_index() has now been deprecated and will
- be removed in 3.21
- - Support of MPI_Type_create_subarray
- - SMPI will now crash and not just warn when encountering an unimplemented
- call. Some exceptions are set (mainly for errhandler calls).
- - MPI_Sendrecv was behaving badly when MPI_PROC_NULL was sender or receiver.
-
- Build System:
+ Build System and other cleanups:
+ - Remove unused run-time parameter "tracing/onelink-only".
- SimGrid now works with intel compilers (MC still buggy)
+ - Remove XBT_LOG_CONNECT, it should be useless nowadays.
PLATFORM:
- Rename FULLDUPLEX into SPLITDUPLEX (old name still accepted)
- TRACING
- - Remove unused run-time parameter "tracing/onelink-only".

Fixed bugs:
+ - #194: Feature request: simgrid::s4u::Comm::test_any()
- #245: migrating an actor does not migrate its execution
- #254: Something seems wrong with s4u::Actor::kill(aid_t)
- #256: Modernize FindSimGrid.cmake
- #257: Fix (ab)use of CMake install
