+ topo_parameters="h;m1,...,mh;w1,...,wh;p1,...,ph" parameters for cluster tag
+ - see examples/platforms/torus_cluster.xml and
+ examples/platforms/fat_tree_cluster.xml
+ * More documentation
+
+ SMPI:
+ * Hostfiles support host:nb_processes construct to deploy several processes on
+ one node.
+ * Collective communication algorithms should not crash if used with
+ improper number of nodes and report the error.
+ * SMPI now partially supports MPI_Topologies : MPI_Cart_create, MPI_Cart_shift,
+ MPI_Cart_rank, MPI_Cart_get, MPI_Cart_coords, MPI_Cartdim_get,
+ MPI_Dims_create, MPI_Cart_sub are supported.
+ * New interface to use SMPI programmatically (still depends on MSG for
+ some parts, see examples/smpi/smpi_msg_masterslave) :
+ - SMPI_app_instance_register(const char *name, xbt_main_func_t code,
+ int num_processes)
+ - SMPI_init()
+ - SMPI_finalize();
+ * Global variables privatization in MPI executables is now performed at runtime
+ with the option smpi/privatize_global_variables (default:no).
+ Limitations : Linux/BSD only, with mmap enabled. Global variables inside
+ dynamic libraries loaded by the application are not privatized (static
+ linking with these libraries is advised in this case)
+
+ Tracing:
+ * Options defined in XML work correctly now.
+
+ Java:
+ * New cmake option, enable_lib_in_jar, to control whether native libraries are
+ copied into simgrid.jar or not (ON by default). Use this option if you want
+ to reduce the size of the installed simgrid.jar, *and* the native libraries
+ are kept installed elsewhere.
+ * Surf binding with SWIG (code generated in maintainer mode only):
+ - plugin to handle callbacks
+ - CPU model only for the moment
+
+ Build System:
+ * Supernovae build mode is definitively removed. It was used to improve
+ inlining and inter-module optimizations. It is nowadays superseded by
+ link-time optimizations commonly available in compilers.
+ * Update ns-3 find lib. Bindings for ns-3 should work again now.
+ * Add boost dependency for surf++
+ * Add new macro for tests
+ - ADD_TESH(name <tesh_args>)
+ - ADD_TESH_FACTORIES(name "thread;ucontext;raw" <tesh_args>)
+
+ XBT:
+ * New functions
+ - xbt_bar_t XBT_barrier_init(unsigned int count)
+ - int XBT_barrier_wait(xbt_bar_t barrier)
+ - void XBT_barrier_destroy(xbt_bar_t barrier)
+ * Make the xbt_os_time module public

+SimGrid (3.10) stable; urgency=low
+
+ The Clean Diaper Release, a.k.a. SimGrid is leak-free.
+
+ Java:
+ * Reintegrate Java to the main archive as desynchronizing these
+ package is not acceptable anymore (Java is now considered stable)
+ * Add explicit synchronization facilities through semaphores
+ * Bug fix: Task.setDataSize() only changed the C world, not the value
+ cached in the Java world
+
+ MSG:
+ * Dramatically change the way files are handled. API and internals changed, but
+ this part of MSG was not considered as production grade either.
+ * Add explicit synchronization facilities through semaphores
+ * Add a new function MSG_host_get_process_list()
+ * Preliminary DVFS support (see examples/msg/energy/ for details)
+
+ SMPI:
+ * SMPI is now included directly in the libsimgrid as the windows
+ linker doesn't force us on splitting it anymore.
+ * Improvements of the SMPI replay tool:
+ - Most of the collective communications are now rooted in the same process as
+ in the original application.
+ - Traces now rely on the same MPI data type as the application (MPI_BYTE was
+ used until now). Multiple data types can now be used in a trace.
+ - The replay tool now supports traces produce either by TAU or a modified
+ version of MPE.
+ - Bug Fix: the compute part of the reduce action is now taken into account.
+ - Gatherv collective is now supported
+ - SimGrid (SMPI for now) can generate replay traces as well. Option -trace-ti
+ of smpirun outputs time independent traces for the current run. One file
+ is created per process. If too many processes are simulated, this behavior
+ can be changed to one file for all processes by using the
+ tracing/smpi/format/ti_one_file flag
+ * smpirun generates the host file if needed (with given host count and platform)
+ * Integration of more than 100 STAR-MPI, MPICH, OpenMPI collective algorithms
+ - allows to select one in particular with --cfg=smpi/coll_name:algorithm
+ - allows to use the decision logic of OpenMPI(1.7) or MPICH(3.0.4) by setting
+ --cfg=smpi/coll_selector:(mpich/ompi)
+ * Support for new functions : MPI_Issend, MPI_Ssend, Commutative operations in
+ Reduce
+ * Add a --cfg:tracing/smpi/internals option, to trace internal communications
+ happening inside a collective SMPI call.
+ * Fix the behavior of complex data types handling.
+ * Make MPI_Wtime another synchronization point to take computations into
+ account.
+ * Replace MPICH-1 test suite by the one from MPICH 3.0.4. Can be built using
+ enable_smpi_MPICH3_testsuite flag in cmake. Run with ctest.
+ * Add all missing Fortran bindings, SMPI should work with Fortran 90
+ (no privatization of global variables yet)
+ * Preliminary DVFS support (see examples/smpi/energy/ for details)
+
+ Model-Checking;
+ * Verification of liveness properties is now available for SMPI applications
+ (in addition to MSG applications)
+ * Bugged examples using SMPI in examples/smpi/mc/
+ * Add --cfg=model-check/visited option. Allows the verification of infinite
+ programs. Detection of loops in the execution thanks to the system state
+ comparison and reduction of the state space to explore. Can be combined with
+ DPOR for safety properties.
+
+ SimDag:
+ * Allow to change SimGrid configuration (see --help) within the code
+ thanks to SD_config() as it can be done in MSG.
+ * Add a new function SD_task_set_amount() upon user request.
+
+ PLATFORM:
+ * Handle units for values (10ms, 10kiloflops, 10Bps, 1GB, ...)
+ * Remove rule based routing (no more PCRE dependency)
+ * Add a limiter_link option to cluster tag, to specify a maximum reachable
+ bandwidth in fullduplex mode when it is less than twice the nominal bandwidth.
+ * Add a loopback_bw and loopback_lat options to cluster tag.
+ * Fix the peer tag that could not be mixed with other AS within a Vivaldi
+ routing. Now peers are encapsulated in an AS and have their own private
+ router but this is transparent.
+
+ XBT:
+ * Our own implementation of getline is renamed xbt_getline, and gets
+ used even if the OS provide a getline(). This should reduce the
+ configuration complexity by using the same code on all platforms.
+ * New type: xbt_cfg_elm_boolean.
+ * Allow to use yes/no for boolean configuration options in the command line.
+ * Allow to disable SimGrid cleanups at exit from command line option.
+ There are situations where one may want a simulation to end with an exit.
+ Unfortunately, calling exit may cause SimGrid to segfault, which is quite
+ annoying when scripting around the simulator. Adding a
+ --cfg=clean_atexit:no allows to circumvent this issue.
+
+ Build System:
+ * Lots of memory leaks were corrected in this release.
+ There is no known memory leaks anymore, in all of our 600+ tests.
+ * New command line option --version, to get SimGrid version information.
+ Packagers may want to add extra words to SIMGRID_VERSION_EXTRA defined in
+ CMakeLists.txt.
+ * Supernovae builds are deprecated, and expected to be removed in the next
+ version of SimGrid.

+
+SimGrid (3.9) stable; urgency=low
+
+ The Grasgory release: GRAS is really dead now.
+
+ * Complete overhaul of the internal host structures scheme.
+
+ GRAS:
+ * If you use GRAS, you should stay at SimGrid 3.5 (at most) since it
+ was considered as experimental and badly maintained since then.
+ * Keeping it was thus a trap to our potential users, that could take
+ it instead of MSG or SMPI by mistake despite is pity state.
+ * GRAS seems to have very few users (if any), and no one volunteered
+ to maintain it further. It also induces a lot of XBT code (for
+ portability sake), that must be maintained too.
+ * For all these reasons, we killed GRAS. If someone wants to revive it
+ in the future, don't cry, our git history still remembers of GRAS.
Documentation:
- * Split the doc into a user guide and a reference guide.
+ * Major overhaul. Merge our documentation again as time proved that
+ splitting it was really not helping our users.
+ * Further improve the developer documentation to help newcomers
+ hacking on SimGrid itself. The user documentation (and in
+ particular, the beginner documentation) is still in a sorry state.
+
+ SMPI:
+ * Now works on Windows too!
+ * Much more extensive test suite, from MPICH
+
+ SIMDAG:
+ * Add a new loader (SD_PTG_dotload) that creates a parallel task graph
+ (i.e., a DAG whose nodes are parallel tasks) from a dot file. Creates a
+ dynar of SD_TASK_COMP_PAR_AMDAHL and SD_TASK_COMM_MXN_1D_BLOCK tasks.
+ * Bug fix: let task be scheduled when the last dependency to be solved is
+ a control dependency.
+ * Remove SD_load_environment_script function.
+ Use the C sg_platf function if you want to declare a platform
+ programmatically.
+
+ MSG:
+ * New function: MSG_process_get_number()
+ * Old function documented: MSG_config()
+ * Remove MSG_load_platform_script function
+ Use the C sg_platf function if you want to declare a platform
+ programmatically.
+
+ SURF:
+ * Change the default value of the TCP_gamma constant (maximal size of TCP
+ congestion window) to a more realistic 4MiB value. If you notice changes in
+ your simulation results, you can fall back to the previous 20k tiny window
+ by adding --cfg=network/TCP_gamma:20000 on command line.
+ * (Hopefully) fix a bug wrt periodic availability and state traces
+ * Bug fix: use default values at start when first event in availability/state
+ trace is not at time 0.
+
+ PLATFORM:
+ * remove the "new_" part of function name sg_platf_new_trace_connect
+ (resulting in sg_platf_trace_connect), since it does not create
+ anything new
+
+ XBT:
+ * Kill synchronized dynars, and xbt_dynar_dopar(). We cannot think of a
+ use case where it's really mandatory, and maintaining it was a pain in
+ our code base.
+ * New: xbt_fifo_search(), search an item with a user-provided
+ comparison function instead of dumb pointer comparison.
+
+ LUA:
+ * Fix the lua deployment:
+ Use `simgrid.init_application()` before deployment instead of
+ `simgrid.msg_register_application()` after.
+
+ TRACING:
+ * Transfer the tracing files into the corresponding modules.

- * Add an interface to execute cleanup functions when a process is killed,
- to avoid memory leaks.
* Add an interface to auto-restart processes when the host in which they are
executing comes back.
+ * Ensures that SIMIX_clean is called automatically. It's not part of

+ when comparing doubles. Sometimes they are different for non significant
+ digits only.
* New types of typed tasks. SD_TASK_COMP_PAR_AMDAHL represents a
parallel task whose initial work is distributed among host according
to the Amdahl's law. Such tasks are created with a parameter alpha

+ * Correct behavior of smpi/sender_gap and set its default value to 0
+ * Add option to asynchronously send small messages to allow better
+ simulation of pt2pt communications. --cfg=smpi/async_small_threshold:value
+ specifies the size in bytes under which messages will be asynchronously sent.
+ * Add support of MPI_Iprobe, MPI_Probe, MPI_Testall, MPI_Wtick functions
