SMPI
* New Model SMPI (three-interval linear regression for correction factors)
See RR-7426, available at http://hal.inria.fr/inria-00527150
- * Ability to use fortran MPI code (through f2c, automatically privatized)
+ * Ability to use FORTRAN MPI code (through f2c, automatically privatized)
* New MPI functions supported: MPI_Get_count(), MPI_Comm_split()
* New: RAM folding (see RR-7426 and examples/smpi/NAS/DT-folding)
* New: execution sampling (see RR-7426 and examples/smpi/NAS/EP-sampling)
* See also src/smpi/README

* Tracing system
- - tracing API for MSG changes: TRACE_start has no
- longer parameters, the trace file is supplied through
- an option passed to simulator. Categories declaration
- and utilization remain the same. The following options
- are supported:
+ - Tracing API changes: TRACE_start and TRACE_end should not be called
+ by user-code. They are automatically called by simulators created
+ with SimDAG, MSG and SMPI if the toolkit is compiled with
+ tracing_enabled=ON. Categories declaration and utilization remain the
+ same for MSG and SimDag.
+ - A function was added to the tracing API to declare categories with
+ colors:
+ - TRACE_category_with_color (char *category, char *color)
+ where color must be in the following format
+ "%f %f %f", red, green, blue
+ and red, green, blue are float values in the interval [0, 1]
+ - User can specify NULL as color parameter, or continue calling
+ TRACE_category (cat)
+ On that case, the tracing system will define random colors
+ - The following command-line options are supported:
--cfg=tracing/filename:msg.trace
+ --cfg=tracing:1 (activate tracing, needed to use others)
--cfg=tracing/platform:1 (categorized resource use)
+ --cfg=tracing/uncategorized:1 (uncategorized resource use)
--cfg=tracing/msg/task:1 (task creation)
--cfg=tracing/msg/process:1 (process creation, migration)
- --cfg=tracing/msg/volume:1 (volume of msg send/recv)
- --cfg=tracing/smpi:1 (smpi interface tracing)
+ --cfg=tracing/msg/volume:1 (volume of MSG send/recv)
+ --cfg=tracing/smpi:1 (SMPI interface tracing)
+ --cfg=tracing/simdag:1 (allow SimDAG tasks receive categories)
- examples of examples/msg/tracing updated
+ * Tracing SimDag
+ - DAXLoader and DOTLoader functions can generate tasks with categories
+ - A new function to attribute a category to SD tasks:
+ TRACE_sd_set_task_category (SD_task_t task, char *category)
* Tracing the MPI interface implemented by SMPI
- Collective operations are traced with states
- Point-to-Point operations are traced with states/links
* New function SD_workstation_get_current_task() that returns the kind
of task currently running on a workstation in the sequential access
mode.
- * Raise some warnings when unexecuted remains at the end of the
+ * Raise some warnings when unexecuted tasks remains at the end of the
simulation. This is usually caused by cycles in the DAG.
SIMIX
* Port to windows ( TM :)
* Fix the 'make install' target.
No need to use 'make install-simgrid' anymore
- * Introduce a 'make dist' target compiling a *souce* archive
+ * Introduce a 'make dist' target compiling a *source* archive
'make package' compiles a binary archive
* Compile java files only on need
* Add --cd and --setenv command line options to tesh
LUA Bindings
* Add layer to set up environment directly from lua, without XML.
- * The effect of gras_stub_generator can be achieved athrough
+ * The effect of gras_stub_generator can be achieved through
lua too (check examples/gras/console/ping_generator.lua)
