Re: [gem5-users] dump stats for every N cycles

[Sascha Bischoff]

Hi Shervin,

You can turn it off by setting the period to 0. Unless you do this there is no 
upper limit, and it will keep running to the end of the simulation.

I'm not sure how you do this once the simulation is running though.

Hi Sascha,

Thank you very much for your guidance. Having periodicStatDump, I want this 
function to run for a certain duration of time. For example periodicStatDump, 
dumps stats every N cycles FROM tick t1 TO tick t2. Could you please let me 
know how I can do that?

Regards,
Shervin

Hi Shervin,

Try updating your gem5. The patch which enables this only recently got 
committed to the repository (about 2 weeks ago).

The definition is in src/sim/stat_control.cc, and the swig interface is in 
src/python/swig/stats.i.

Hi Sascha,

I added "from m5.internal.stats import periodicStatDump as statDump" to fs.py, 
however while building gem5, it gives me the following error:

can not import name periodicStatDump

I can not find the definition of "periodStatDump" function in any of the python 
files. I would appreciate if you could help me with this.

Thanks,
Shervin

Hi Shervin,

You want to add the following to one of your python files (fs.py, se.py
are good choices):

from m5.internal.stats import periodicStatDump as statDump
# Specify the period in Ticks
statDump(1000000000)

I hope that helps,

Sascha
