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).
+
Documentation:
* Split the doc into a user guide and a reference guide.
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
+ 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.
Simix:
* Bug fixes around the resource failures: don't let the processes
- survive the host they are running onto
+ 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 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.
- 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.

+ 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.
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.
-- $date Da SimGrid team <simgrid-devel@lists.gforge.inria.fr>
- Add new runtime parameters --help-logs and --help-log-categories
to display informations about supported logging parameters and
categories.
- - Old deprecated parameters --{gras,surf,msg.simix,xbt}-log=...
+ - Old deprecated parameters --{gras,surf,msg,simix,xbt}-log=...
don't exists anymore.
* Mallocators: allow value NULL for the reset function.
* Dicts:
