SimGrid (3.8) NOT RELEASED; urgency=low
The "SimGrid makes psssshiiiit and jumps into the cloud" release.
-
- CMAKE:
- * Remove option custom_flags. Now use environment variables CFLAGS
- and LDFLAGS.
-
+
MSG:
* Add an experimental interface to manipulate VMs. They are mainly
process groups with very few intrinsic semantic, but they should
allow you to build the semantic you want easily.
+ * New function: MSG_host_set_property_value()
+ * Deprecate functions MSG_global_init() / MSG_global_init_args()
+ Please use MSG_init() instead. (reducing the amount of entry
+ points in the library helps us).
+ * Make it impossible to link against the wrong version of the lib
+ * Bug fixes that made the host (and link) failures unusable.
+ * Add a way to auto-restart process when the host in which they are
+ executing comes back (ON_FAILURE="RESTART" on deployment file,
+ MSG_process_auto_restart_set).
+ * Use the "msg_" prefix for all datatypes (instead of m_, msg_ and MSG_),
+ please stop using the old ones, they are DEPRECATED.
+ * Deprecate MSG_clean(). No need to call it anymore.
+ * Function MSG_get_host_number() is not deprecated anymore.
+
+ Documentation:
+ * Split the doc into a user guide and a reference guide.
+
+ Cmake:
+ * Remove option custom_flags. Now use environment variables CFLAGS
+ and LDFLAGS.
+ * Enable tracing by default. This modules rocks you should use it.
+ * Use default cmake things to detect lua instead of home grown ones.
+ * New option "enable_mallocators" to disable mallocators, for debugging
+ purpose ("on" by default).
+
+ Simix:
+ * Bug fixes around the resource failures: don't let the processes
+ survive the host they are running onto.
+ * 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
+ the public interface anymore (bindings should be updated).
SimDag:
- * New type of typed tasks SD_TASK_COMP_PAR_AMDAHL that represents a
+ * Bug fix for when SD_Simulate is called with a positive value: be careful
+ 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
that corresponds to the non-parallelizable part of the computation.
-
- Before calling SD_task_schedulel or SD_task_schedulev, the
- SD_task_distribute_comp_amdahl function has to be called with the
- desired number of workstations. The filling of computation_amount and
- communication_amount (actually empty) structures is then done
- seamlessly.
+ SD_TASK_COMM_PAR_MXN_1D_BLOCK represents a complex data redistribution
+ between two sets of workstations assuming a 1D block distribution (each
+ workstation owns a similar share of data) on both sides.
+
+ These tasks can be scheduled with SD_task_schedulel or SD_task_schedulev.
+ Data redistribution will be automatically scheduled once parent and child
+ are both scheduled. The filling of computation_amount and
+ communication_amount structures is now done seamlessly thanks to the chosen
+ assumptions.
* New function SD_workstation_dump to display various information
+ * New function SD_task_set_rate to throttle the bandwidth allowed to be used
+ by a SD_TASK_COMM_E2E typed task. This rate depends on both the nominal
+ bandwidth on the route onto which the task is scheduled and the amount of
+ data to transfer.
+ To divide the nominal bandwidth by 2, the rate then has to be :
+ rate = bandwidth/(2*amount)
+ * Compute tasks that have failed can now be rescheduled and executed again
+ (from their beginning)
+ * Increasing source code coverage (src/simdag is now covered at 95.8%
+ on average)
+
+ SMPI:
+ * Re-implement time-independent trace replay using SMPI (at the
+ smpi_smp_* level) instead of MSG. This should replace
+ examples/msg/actions/actions.c
+ * Implement the exchange of non-contiguous data.
+ [Khalid Hasanov & Jean-Noel Quintin] Thanks for the patch, guys.
+
+ SimGrid:
+ * Export a sg_cmdline dynar containing all the arguments we got from
+ the command line.
+
+ XBT:
+ * Functions xbt_dict_hash() and xbt_dict_hash_ext() are made public,
+ and renamed to xbt_str_hash() and xbt_str_hash_ext().
+ * New function: xbt_os_timer_resume() to restart a timer w/o resetting it.
+ * Greatly improve the robustness of mmalloc to user errors (such as
+ using an area after freeing it, or freeing it twice)

+ We discovered that the Lua console is broken, but we are missing the
+ manpower to fix it right now. The problem existed in 3.7 too, so we
+ are not blocking the release for that. Sorry if you depended on this
+ feature, any help would be really welcome.
