SimGrid (3.15) UNRELEASED; urgency=low
- The Ever Green Release.
+ The Spring Release: continuous integration servers become green
We fixed even the transient bugs on all target architectures:
Linux (CentOS, Debian, Ubuntu, Fedora), Mac OSX (Mavericks, El Capitan)
Windows, FreeBSD, NetBSD.
- Kill the obscure NativeException. Nobody want to survive the issues
it denotes, so use JniException that is a RuntimeException (not to
be catched explicitely).
+ - Fix numerous memleaks all around the place. In particular, around VMs.
S4U
- New callbacks:
- Links are now usable from s4u
- New: Engine::hostList() and Engine::hostCount(). Still clumsy.
- Drop Host::getPstateSpeedCurrent() which dupplicates Host::speed()
+ - New examples, converted from MSG.
SimDag
- Backwards Compatibility breaks
Macros ensure the backwards compatibility, but you should fix your code
SMPI
- - Major C++ rewrite ongoing (SMPI used to be C compiled in C++). This can break codes that were using internals of SMPI (from private.h instead of the public smpi.h).
- - Bump our claim of support from MPI 1.1 to MPI 2.2. We don't support 100% of
- it, but it should be enough. Contact us if not.

- MPI_Win_lock/unlock support added (as for all RMA, implementation is naive and probably inaccurate)
- New algorithm for SMPI_SHARED_MALLOC: global, where all blocks are
- mapped onto a unique file.
- - Bugfix : smpirun was sometimes misusing hostfile when wrongly terminated
- - Fortran : cleanups, fixes, support of user-added operations
- - RMA : MPI_Accumulate are applied in correct order, and
- MPI_Win_complete or MPI_Win_post shouldn't miss messages anymore.

- Better support for MPI_IN_PLACE
- Support for MPI_Win attrs and keyvals.
- Support MPI_Comm_group_create, MPI_Type_size_x

-The Ever Green Release.
+The Spring Release: continuous integration servers become green.
- * Continuous integration tasks are green (no more transient errors)
- * S4U pushed further, integrating more parts of SimDag.
- * Start converting the SMPI internals to C++ too. TBC.
+ * S4U: progress, integrating more parts of SimDag; New examples.
+ * SMPI: Support MPI 2.2; Convert internals to C++ (TBC).
+ * Java: Massive memleaks and performance issues fixed.
* Plus the usual bug fixes, cleanups and documentation improvements
