+SimGrid (3.16) UNRELEASED
+
+SimDag
+ - New and Backwards Compatibility break:
+ 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.

+
+SimGrid (3.15) stable; urgency=low
+
+ 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.
+
+ - 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: MSG_process_yield(). Stop and yield to other processes.
+ - New: MSG_process_daemon(). Daemon processes are automatically killed
+ when the last non-daemon process terminates
+ - 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: duplicates 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 caught explicitly).
+ - Partial bug fix in initialization. SimGrid flags on command line were
+ consumed at C level but stayed in the original Java String[] args.
+ This could mess users' args[i] if SG flags were not put at the end of
+ the command line.
+ The SimGrid flags are now removed from the Java arguments. However,
+ the number of arguments REMAINS UNCHANGED. It is then UNSAFE to test
+ if args.length is greater than the number of YOUR OWN ARGUMENTS.
+ It might be if you have --log or --cfg flags in the command line.
+ - Fix numerous memleaks all around the place. In particular, around VMs.
+
+ 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
+ - New: Engine::hostList() and Engine::hostCount(). Still clumsy.
+ - New: Actor::suspend(), Actor::resume(), and Actor::migrate(new_host)
+ - New examples: The conversion of MSG examples to S4U has begun
+ - Actors: create, kill, migration, and suspend
+ - Applications: master-worker and token-ring
+ - Action replay: communications and storage
+ - Drop Host::getPstateSpeedCurrent() which duplicates Host::speed()
+
+ 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
+ - 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, MPI_Get_accumulate 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 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.
+
+ 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.
