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 do wrong simplifications.
+ That's a point in the routing algorithm, let's avoid wrong simplifications.
MSG
- - New function: MSG_process_yield()
+ - 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: dupplicates MSG_host_get_speed
Java
- Ensure that an actor can kill itself with Process::exit()
S4U
- New callbacks:
- - simgrid::s4u::onPlatformCreated: right before the simulation starts
- - simgrid::s4u::onSimulationEnd: right after the main simulation loop
+ - 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.
+ - Drop Host::getPstateSpeedCurrent() which dupplicates 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+ - The SD_route_bandwidth and SD_route_latency functions have been replaced by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 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.
+ - 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
+ - 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.

* 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.
MSG:
* Memory usage should be decreased for simulations with a large number
- of processes. This also helps for SMPI.
