-SimGrid (3.9) NOT RELEASED; urgency=low
+SimGrid (3.10) NOT RELEASED; urgency=low
+
+ 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 xbt_cfg_elm_boolean type
+
+ 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
+ * Bugfix: 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
+
+ SMPI:
+ * SMPI is now included directly in the libsimgrid as the windows
+ linker dont forces 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 datatype as the application (MPI_BYTE was
+ used until now). Multiple datatypes 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.
+ * smpirun generates the hostfile if needed (with given hostcount and platform)
+
+ PLATFORM:
+ * Handle units for values (10ms, 10kiloflops, 10Bps, ...)
+ * Remove rule based routing (no more pcre dependency)

+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.
Documentation:
* Major overhaul. Merge our documentation again as time proved that
- spliting it was really not helping our users.
- * Further improve the developer documentation to help newcommers
+ 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.
* Now works on Windows too!
* Much more extensive test suite, from MPICH
-SIMDAG:
- * Bug fix: let task be scheduled when the last dependency to be solved is a
- control dependency
+ 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.
- * Bug fix about the way periodic availability/state traces are handled.
- * Bug fix: use default values at start when first event in availability/state
+ * (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
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.
