SimGrid (3.6) unstable; urgency=low
+ MSG
+ * Change the prototypes of action replay. Sorry for inconvenience,
+ but this is really more efficient this way.
+ * Kill the braindead MSG_task_refcount_dec() function. I guess nobody
+ ever managed to do anything useful with it.
+
SURF
* New model for multi-core CPUs. You can now use the core attribute to
precise the number of cores of a host. This is a basic model. Every
Simix
* Completely rewrote this module to allow parallel execution.
+ * Introduce a new context factory "raw", highly inspirated from the
+ context factory, but using manually crafted functions in assembly to
+ do the work in an efficient manner.
+ * Allow to change the used context factory at run time, not only at
+ compilation time. Use --cfg=simix/context:raw for maximal speed.
XBT
* Add a new function xbt_dynar_to_array that transforms a dynar into a
NULL-terminated array. This may solve backward compatibility issues
due to the change to return type of SD_Simulate. See also:
http://lists.gforge.inria.fr/pipermail/simgrid-user/2010-December/002206.html
+ * Add new logging macros, with variable number of arguments.
+ * Kill old style logging macros.
+
+ INSTR
+ * New configuration options
+ Options triva/categorized and triva/uncategorized can be used to generate
+ graph configuration files for Triva visualization tool.
+ * Configuration option tracing/platform is renamed to tracing/categorized
+ * XBT logging makes tracing error checks easier, new root log hierarchy: instr
+ * New TRACE_user_link_variable interface:
+ User provides the name of the link and the tracing variable to attach to it
+ * the declaration of tracing categories must be done after the environment creation
+ * simpler tracing interface, just one way to declare categories
+ TRACE_category or TRACE_category_with_color, it is up to you
+ * links in the trace file are again identified by their names
+ * trace contains the full platform hierarchy exactly as declared using the ASes
+ * Options tracing/msg/[task|process]:1 groups the process by hosts
+ for both cases, tasks and processes must have names that are unique during the simulation
+ these options generate traces that are suited to gantt-charts, such as the space-time view of Paje
+ * The experimental option tracing/msg/volume is deprecated
+ its functionality may be reincorporated if needed
