Hi,

I am interested in injecting prerecorded traces into a Ruby system using the TrafficGen object. However I'm encountering difficulties in establishing the connection between them. E.g., Is it necessary for connect TrafficGen to a sequencer to interface with Ruby? Are there any available examples or references that could assist me in this process?

Best,
David

Hi David,

If these “prerecorded traces” are not recorded using the standard gem5 cpu tracer (elastic traces), you will likely need to roll your own trace-based traffic generator.

TrafficGen is likely not the tool you are looking for. TraceCPU might be a closer match. You can watch at the code that relates to TraceCPU as well as to etrace_replay.py to see how to configure a system with a trace replayer.

Regards,
