Hello,
I did not edit CommMonitor.py yet have that line and checking further, both
master and hpca branches have it as well:
https://gem5.googlesource.com/public/gem5/+/master/src/mem/CommMonitor.py#50
https://gem5.googlesource.com/public/gem5/+/hpca/src/mem/CommMonitor.py#50
Might there be another problem? Sorry if I am misunderstanding anything there.
For src/cpu/BaseCPU.py, you should first import CommMonitor and MemTraceProbe
then edit the function "addPrivateSplitL1Caches":
...
#self.dcache_port = dc.cpu_side
self.monitor = CommMonitor()
self.monitor.trace = MemTraceProbe(trace_file="l1trace.trc.gz")
self.dcache_port = self.monitor.slave
self.monitor.master = dc.cpu_side
..
Cheers
Serhat Gesoglu

Sorry I meant,
Firstly, had I not added this line system = Param.System(Parent.any, "System
that the monitor belongs to.") in the CommMonitor.py then I'm getting an error.

PFA. But as you suggested, I didn't actually attach a MemTraceProbe to the
commMonitor. Please tell me, how should I proceed.
Thank you

Hello,
I believe you do not need to change anything on CommMonitor.py. Did you follow
the instructions here and attach a probe to the monitor you are using:
http://gem5.org/General_Memory_System#Traffic_analysis_and_memory_trace_capture
?
Cheers

Subject: [gem5-users] CommMonitor.cc not generating trace file
Hi,
I added CommMonitor between cpu and L1Dcache. I'm using the current gem5 from
the github and updated to the branch hpca.
The CommMonitor is seen in the config.dot.pdf file generated. PFA. But the
trace file is not getting generated in m5out directory. Actually, the
CommMonitor.py does not even have the argument trace_file, the first time I ran
the simulation. I then added the argument in that file. There is a lot of
difference between the comm_monitor.cc file that is there with me and that in
the the last stable version.
I used detailedcpu with l1i_cache and l1d_cache. Kindly, help me in generating
the trace file.
Thank you in advance
Varun
