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.
* 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
+ * Cleanup the exceptions that may get thrown by each function
+ * Other internal cleanups in Java bindings. Performance still bad :/
+ 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.
+ * Fix SD_task_unschedule() on typed tasks
+ * Fix SD_task_get_execution_time() to return seconds, not flop*sec
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.
+ * Rename MSG_TIMEOUT_FAILURE into MSG_TIMEOUT for sake of logic
+ * Add a MSG_task_set_data() function
+ * About trace replay (see examples/msg/actions):
+ - implement barrier
+ - Allow to work with splitted trace files for each process
+ - Fix implementation of collective operations
+ SMPI:
+ * This is the first release of SimGrid where SMPI is not considered
+ beta anymore (even if some corners should still be improved)
+ * Port over the new SIMIX_network submodule (internal refactoring)
+ * Basic support to log events as with SMPE (use --cfg=SMPE:1)
+ * Implement more missing elements of the standard:
+ - MPI_COMM_SELF
+ - MPI_MAXLOC MPI_MINLOC + all associated datatype MPI_DOUBLE_INT,
+ MPI_FLOAT_INT, etc.
+ - MPI_Address() MPI_Get_count() MPI_Type_free() MPI_Type_extent()
+ MPI_Scan() MPI_Get_processor_name()
+ - Added implementation of missing case for Alltoall (warning: it's
+ *not* the bruck variant from OpenMPI; based on Alltoallv instead)
+ - SMPI_MPI_Gather() SMPI_MPI_Gatherv() SMPI_MPI_Scatterv()
+ SMPI_MPI_Reduce_scatter() SMPI_MPI_Allgather()
+ SMPI_MPI_Allgatherv()
+ * Bug fixes include:
+ - MPI_Waitsome() was broken
+ - Allow relative includes in smpicc
+ - Command line cfg argument 'reference_speed' was ignored...
+ - Some functions did not properly lead to auto-benching of user code
+ - smpicc passes -O2 by default (just like openmpi one)
+ SIMIX:
+ * add SIMIX_action_suspend() and SIMIX_action_resume() functions
+ * add SIMIX_message_sizes_output() as a pimple to write to file the
+ amount of messages per size. Use gnuplot to get histogram.
+ Pimple because that's the only user-visible function of simix,
+ defined directly in xbt.h (irk, sorry)
+ * About semaphores:
+ - Add a SIMIX_sem_get_capacity() function
+ - Fix interactions with processe resume/suspende
+ - release_forever() was stupidly broken
+ - Fix SIMIX_display_process_status() for processes in a semaphore
+ - Make SIMIX_sem_block_onto() user-visible
+ * Refactoring context stuff:
+ - Use pseudo-OOP for better modularity
+ - reimplement SIMIX_process_kill() without process_schedule() so
+ that the latter can take as invariant that it is called from
+ maestro.
+ - Merge context_start into context_new for sake of simplicity
+ 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
+ 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).
+ * Allow to use xbt_dynar_shrink() to expend the dynar instead
+ 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)
