- 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
- * 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:yes allows to circumvent this issue.
+ 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
+ * Kill support for 32bits host architecture.
+ - Integers are too short to store a date or a size
+ - Plus, less platforms ~> simpler codebase ~> easier to maintain

+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
- * Bugfix: Task.setDataSize() only changed the C world, not the value
+ * Bug fix: Task.setDataSize() only changed the C world, not the value
cached in the Java world
MSG:
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
- 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)
+ - 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
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
- * replace MPICH-1 test suite by the one from MPICH 3.0.4
+ * 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
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.

+ annoying when scripting around the simulator. Adding a

+
+ 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.

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.
