+ Msg
+ * New function: MSG_load_platform_script()
+ to make possible using a lua script instead of XML files to set up platforms
+ * New function: MSG_set_function
+ to associate functions to processes, used when bypassing the parser
+ Lua Bindings
+ * add layer to set up environment and bypass the XML surf parser
+ * modify the entry point, to take into consideration when lua is used only as a platform generator
+ SURF
+ * add new callbacks to the CPU & netwok models to create resources
+ no need to pass through the parser callbacks to do so.
+ * add new function to create routes table via the routing model
+ * add generic functions in the public interface
+ that allows the user to call SURF 'create_resource' methods from a lua script.
+ SIMIX :
+ * New function: SIMIX_process_set_function()
+ called by MSG_set_function
SimDag
-
* Change the way a task is considered as ready. Instead of removing
dependencies when a task is done, a counter is decreased. This way,
it is always possible to reach ancestors thanks to the
simulated" (SD_RUNNABLE) used by the simulation kernel.
* Add an example that scheduling a DAX on an heterogeneous platform
using a Min-Min strategy
-
+ * new function SD_dotload(char*) to load a DAG described in dot
+ format. This loader and the corresponding examples require the
+ installation of the graphviz library.
+
+ SIMIX
+ * Change the underlying waiting queue in semaphores so that a process
+ can wait on several of them simultaneously (as in waitany).
+ * Fix the way to handle tokens in semaphores so that all access patterns
+ work: {acquire, acquire_timeout, waitany} / {release, release_forever}.
+
XBT
* New data container: setset (set of sets of elements)
* New module: mmalloc (mapped malloc)
'make package' compiles a binary archive (not well tested)
* Compile java files only on need
+ Tracing:
+ * 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:
+ --cfg=tracing/filename:msg.trace
+ --cfg=tracing/platform:1 (categorized 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)
+ - examples of examples/msg/tracing updated
+
+ * Tracing the MPI interface implemented by SMPI
+ - Collective operations are traced with states
+ - Point-to-Point operations are traced with states/links
+ - Tracing activated by a parameter "-trace filename" passed
+ to smpirun during execution (considering that simgrid
+ is compiled with tracing enabled)
+ - To run the simulation with gdb, the simulator
+ accepts --cfg=tracing/smpi:1 to trace SMPI
+ - tesh files to check if smpi tracing is ok
+
+ * GTNetS tracing re-worked
+ - adaptation to the tracing system of GTNets to cope
+ with modifications regarding the fullduplex mode
+ - new tesh files to check if gtnets tracing is ok
