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.
- New: MSG_process_ref/unref(). Fiddle with the process refcounting.
- Renamed MSG_energy_plugin_init() -> MSG_host_energy_plugin_init()
to make room for the upcoming network energy plugin.
+ - Drop MSG_host_get_current_power_peak: dupplicates MSG_host_get_speed
Java
- Ensure that an actor can kill itself with Process::exit()
- 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:
- s4u::Host::onSpeedChange: when the pstate is changed, or when an
event from the availability_file changes the avail speed.
- 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
- - 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.
+ - Major C++ rewrite ongoing (SMPI used to be C compiled in C++).
+ This can break codes using SMPI internals (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.
+ mapped onto a unique small file using some system magic.
+ - 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.
+ - RMA: MPI_Win_{complete/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
+ - MPI ops should be properly applied to all allowed types
- Replace implementation of MPI_Bcast "scatter followed by rdb allgather"
algorithm by a non failing one from mpich.
