+SimGrid (3.15) UNRELEASED; urgency=low
+
+ The Ever Green Release.
+ We fixed even the transient bugs on all target architectures:
+ Linux (CentOS, Debian, Ubuntu, Fedora), Mac OSX (Mavericks, El Capitan)
+ Windows, FreeBSD, NetBSD.
+
+ - Rename NetCards to NetPoints.
+ This was intended to help NS3 users, but that's not a netcard.
+ That's a point in the routing algorithm, let's avoid wrong simplifications.
+
+ MSG
+ - New function: MSG_process_yield()
+ - Renamed MSG_energy_plugin_init() -> MSG_host_energy_plugin_init()
+ to make room for the upcoming network energy plugin.
+
+ 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).
+
+ S4U
+ - New callbacks:
+ - s4u::onPlatformCreated: right before the simulation starts
+ - s4u::onSimulationEnd: right after the main simulation loop
+ - s4u::onTimeAdvance: right after a clock change (time is discrete)
+ - 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
+
+ SimDag
+ - Backwards Compatibility breaks
+ - The SD_route_get_list and SD_route_get_size functions have been removed.
+ They are replaced by the unique
+ void sg_host_route(sg_host_t src, sg_host_t dst, xbt_dynar_t links)
+ The route from src to dst is built in the links dynar whose size can
+ be obtained with xbt_dynar_length.
+ - The SD_route_bandwidth and SD_route_latency functions have been replaced by
+ sg_host_route_bandwidth and sg_host_route_latency.
+ 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.
+ - 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 MPI_Comm_group_create, MPI_Type_size_x
+ - Replace implementation of MPI_Bcast "scatter followed by rdb allgather"
+ algorithm by a non failing one from mpich.
+
+ XBT
+ - Kill the fifo data container: we don't use it anymore.
+
+ XML
+ - A <cluster> can now be created with different speed values to represent pstates.
+ see examples/platforms/energy_cluster.xml for an example.

+
+SimGrid (3.14.159) stable; urgency=low
+
+ The previous release was only a crude approximation of a Pi release;
+ this one should be a bit better.
+
+ - Revert a last minute change that broke on Mac OSX.
+ - Fix the changelog and NEWS files.
+ - Improve the documentation, in particular of the routing module.
+ - Integrate some patches flying around in Debian.

Documentation
* The whole documentation was reworked and reorganized. There is
Infrastructure
* We now need python3 for our testing infrastructure.
+ * Model checking needs libevent
+
+ MC
+ * Now works on FreeBSD
SMPI
+ * Privatization now works on FreeBSD
+
* Privatization is now activated by default in smpirun
You can turn it off with -no-privatize if something goes wrong.
* smpi/cpu-threshold:-1 should become smpi/simulate-computation:no
smpi/running-power is renamed to smpi/host-speed
+ * smpi/grow-injected-times option to enable or disable multiplication of the
+ timings injected in MPI_Iprobe, or MPI_Test. Enabled by default, which can
+ make simulation less precise (but also much faster).
+
+ * smpirun script should be (much) faster for large deployments.
+
+ * SMPI tracing : fixed issue with poor matching of send/receives.
+
+ * Replay : Fix broken waitall
+
New functions and features
* MSG_parallel_task_execute_with_timeout, to timeout computations.
would have hoped here.
* xbt_os_sem_get_value: unused internally, deprecated on OS X El Capitan
* Option network/coordinates is now useless and should be dropped.
+
+ Storage:
+ * Added option storage/max_file_descriptors to allow more than 1024 files opened
+
+ SURF:
+ * Added option maxmin/concurrency_limit to allow more than 100 processes per host
+ * Added Dragonfly topology support
XML:
* Add Exa- and Peta- units such as EiB, EB, Eib, Eb for size, and
* ex/app_tokenring: new example, very similar to the MSG Token Ring
* ex/async_waitAll: new example, on asynchronous communications
- -- $date Da SimGrid team <simgrid-devel@lists.gforge.inria.fr>
+ MSG:
+ * Memory usage should be decreased for simulations with a large number
+ of processes. This also helps for SMPI.
