-SimGrid (3.9) NOT RELEASED; urgency=low
+SimGrid (3.11) NOT RELEASED; urgency=low
+
+ TENTATIVE RELEASE GOALS for 3.11:
+ * Consider the removal of Supernovae mode if no user has manifested since the
+ release of version 3.10.
+ * Switch to tesh.pl, and kill the now unused parts of xbt that seem fragile
+ * Switch to surf++, and reintegrate the hypervisor branch on top of it
+ * Clean up CMake files (may need a full rewrite).
+ Non exhaustive list of subgoals:
+ - Use genuine cmake mechanisms and variables when available,
+ instead of reinventing the wheel.
+ - Correctly determine system and architecture (e.g. x32).
+ - Correctly determine compiler type and version (e.g. clang).
+ - Correctly set compiler flags according to compiler type and version.
+ - Correctly set compiler flags for C++, Java, and Fortran compilers too.
+ - Use git to generate the dist archive. Either use git-archive to
+ generate the tarball, or keep using cmake -E tar, but use git-ls-files
+ to get the list of files to pack.
+ - For Java, add an option to enable/disable the inclusion of the native
+ libraries in the jar file, and avoid to duplicate these files.

+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.
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.
+ 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:
+ * 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
+ * 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
- usecase where it's really mandatory, and maintaining it was a pain in
- our codebase.
+ 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.

Turn model-checking OFF if simulation performance matters to you.
Not enabling it at runtime is not enough, disable it in cmake.
