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
+ * Buffering
+ The tracing generates a trace file with unordered timestamped events,
+ because of the way the core simulator (surf) works. A script available
+ at the tools directory (fix-paje-trace.sh) can be used to put the events
+ in order. We have changed the tracing so it can generate ordered timestamped
+ events in the final trace, but depending on the simulator (and how much time
+ is simulated) that can lead to a huge memory utilization. It is desactivated
+ by default, but it can be activated using the --cfg=tracing/buffer:1 switch.
Build Infrastructure
* Define a SIMGRID_VERSION macro in simgrid_config.h.
