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
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.
+ 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,
* 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 a SIMIX_sem_get_capacity() function
+ * 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
* 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)
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)
