+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
+ * add SIMIX_action_suspend() and SIMIX_action_resume() functions
+ * Bugfix: Handle correctly the resume/suspend of processes when they
+ are blocked on semaphores.
+ 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).
+ Tracing for Visualization:
+ * SimGrid is now instrumented in order to generate a trace file for
+ visualization analysis: to use it, need to compile SimGrid with the
+ "tracing" option enabled, and instrument the program using SimGrid with
+ TRACE_start, TRACE_category, TRACE_msg_set_task_category and TRACE_end
+ (among other functions).
+ * The instrumentation only traces the platform utilization for now
+ * Documentation to use the tracing functions and how to analyze the
+ traces with the Triva tool is written.
+ * More information about: SimGrid FAQ (in the section Tracing Simulations
+ for Visualization)

- The "Desktop Grid needs love too" release.
+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
* Fix a vicious bug in dictionaries inducing that some elements were
not freed on xbt_dict_free()
- -- Da SimGrid team <simgrid-devel@lists.gforge.inria.fr>
+ Portability report of this version:
+ * Main portability targets:
+ - linux (ubuntu (804/810/910) /debian (4/5/testing) /fedora (core11))
+ on (amd64/i386/ia64)
+ - mac leopard on i386
+ Known problems: http://cdash.inria.fr/CDash/index.php?project=Simgrid
+ but nothing critical.
+ * Other platforms: windows, AIX and others were not tested for this release
+
+ Timing report of this version:
+ * Lazy evaluation brings arbitrary speedup (ie, speedup depending on
+ scenario parameters). From 8h to a few seconds in desktop grid settings.
+ * Supernovae brings about 25% speedup on i386.
