+SimGrid (3.3.5-svn) unstable; urgency=low
+
+ The "C spoken, se habla Java, Ruby 話せます, fala-se Lua" release.
+
+ Java Bindings: Various Cleanups
+ * Remove put/get: no need to export deprecated interface in Java
+ Use send/receive instead.
+ * Cleanup the examples and add a README per directory
+ * Remove example autoDestination (that's the only way to go now)
+ * Remove example explicitDestination (was a plain copy of basic)
+ * Make JniException a runtime exception, so that there is no need to
+ declare the fact that you may encounter such a beast. I guess that
+ nobody will ever want to survive such error.
+ * Create specific errors for each MSG case of failure:
+ host failure, transfer failure, timeout, task cancelled
+ Ruby and Lua Bindings: create them
+ * That's new and great, you should try them out.
+ Same functionalities than Java bindings, only even less polished
+ SimDag:
+ * Kill the useless "rate" argument of SD_task_get_execution_time()
+ Everyone used to provide -1 as a value, it was not used, and the
+ semantic of a possible use wasn't even clear.
+ * SD_SCHED_NO_COST: Constant to use as cost in SD_task_schedule()
+ either as comm costs or compute costs to mean that there is no
+ such thing for that specific task.
+ MSG:
+ * In trace replay, allow to have one trace file per process.
+ Give the specific trace file as argument of each process,
+ and call MSG_action_trace_run(NULL)
+ You can still have one merged file for each processes.
+ * Kill the MSG_paje_output() function. It's a noop since 2 years.
+ * Kill MSG_WARNING and MSG_FATAL return codes: they were not used
+ anywere in source.
+ * Add a MSG_task_set_data() function
+ SIMIX:
+ * add a SIMIX_sem_get_capacity() function
+ SURF:
+ * Rename configuration variables to start a hierarchy:
+ o cpu_model -> cpu/model
+ o network_model -> network/model
+ o workstation_model -> workstation/model
+ * New configuration variables:
+ o network/bandwidth_factor: correction to bandwith
+ o network/latency_factor: correction to latency
+ o netwotk/weight_S: correction to the weight of competing streams
+ * Add a long description to the models, that users can see with such
+ argument on the command line: --cfg=cpu/model:help
+ * --help-models display the long description of all known models
+ SMPI:
+ * Implement MPI_Get_count, MPI_MAXLOC, MPI_MINLOC
+ XBT:
+ * config: add the ability to set a default value after registration
+ Does not override any previously set value (e.g. from cmd line)
+ * dict: allow to have integer key and data.
+ When so, you need to use the following functions
+ void xbt_dicti_set(xbt_dict_t dict, uintptr_t key, uintptr_t data);
+ uintptr_t xbt_dicti_get(xbt_dict_t dict, uintptr_t key);
+ void xbt_dicti_remove(xbt_dict_t dict, uintptr_t key);
+ In contrary to regular dicts, the key is not malloced before copy.
+ Mixing scalar and regular elements in the same dict is not tested
+ (but may work).

+SimGrid (3.3.4) stable; urgency=low
+
+ The "Desktop Grid needs love too" release (also called Xmas release).
+
+ Models improvements:
+ * Major speedup in the maxmin system solving by using lazy evaluation
+ Instead of solving completely the maxmin system at each iteration,
+ only invalidate (and recompute) the modified parts.
+ This new feature is enabled in default models but you can try to
+ turn it on with "--cfg:maxmin-selective-update=1" for other models.
+ * Cas01 IMproved as default CPU model
+ This CPU model is the same Cas01 model, but it uses the
+ maxmin-selective-update flag and a heap structure to manage
+ actions on SURF kernel.
+ It reduces the complexity to find the next action to finish and,
+ consequently, it's faster than the old Cas01.
+ This is the new default CPU model (Cas01).
+ * Rename the old Cas01 model to Cas01_fullupdate
+ Keep the old cpu model Cas01 with the new name of Cas01_fullupdate.
+ Use "--cfg=cpu_model:Cas01_fullupdate" to use the old default CPU model.
+ * CpuTI (CPU Trace Integration)
+ A new CPU model whose objective is simulate faster when using
+ availability trace files.
+ Instead of using a full featured, over engineered maxmin system for
+ CPU modeling, this model does the pre-integration of traces files
+ to calculate the amount of CPU power available, and so, executes
+ faster than the old CPU models.
+ Use "--cfg=cpu_model:CpuTI" to change to this CPU model.
+ * Use LV08 as default network model since it gives better accuracy
+ for small messages and shouldn't change things for big ones.
+ Use --cfg=network_model:CM02 to get the previous behavior.
+
+
+ ******************************************
+ *DO NOT MIX 3.3.4 RESULTS WITH OLDER ONES*
+ ******************************************
+ * The new CPU model may changes simulations!
+ The point is that events occurring at the exact same timestamp
+ are not scheduled in the same order with the old and new
+ version. This may be enough to completely change the execution
+ of simulations in some cases.
+ * The new network model will change simulations!
+ This new model is more realistic than the previous one, so you
+ should consider redoing your old experiments with this model.
+ Sorry for the inconvenience.
+
+ Build System:
+ * Introduce the supernovae compilation mode
+ When compiled that way, the whole SimGrid (or almost) is put in a
+ single compilation unit and compiled in one shoot.
+ This is to help gcc which has difficulties to inline stuff from one
+ file into another.
+ The speedup seem to be above 15%, althrough more tests are needed on
+ amd64 to confirm that gain.
