[gem5-users] Re: Using DSENT with on-chip-network-power-area.py

[赵子丰 via gem5-users]

Dear Professor Tushar,
  Can DSENT estimate the  power/area of control module that added 
into the Garnet?


Best wishes,
Zifeng Zhao

  &gt;OR I suggest using garnet to get stats and run DSENT separately.
 I mean get stats for access to links, buffers etc.. and then use some external 
tool (DSENT / anything else) to get energy/access and then estimate the total 
energy.
 
 
 Cheers, Tushar

   Yes the DSENT parsing script seems to be broken. 
 You can try to fix it.

 DSENT is not being actively developed / maintained, but this page has a copy + 
README:

   Hello.
 I want to estimate the power and area of some Network-on-Chip topologies using 
DSENT. I have followed the instructions in gem5-users given by Dr. Krishna 
(https://www.mail-archive.com/gem5-users@gem5.org/msg15749.html)  for this 
purpose.
 
 First, I simulated a Mesh_XY topology with synthetic traffic using this 
command:
 build/NULL/gem5.opt configs/example/garnet_synth_traffic.py --network=garnet 
--num-cpus=64 --num-dirs=64 --topology=Mesh_XY --mesh-rows=8 
&nbsp;--sim-cycles=10000000 --synthetic=uniform_random --precision=3 
--injectionrate=0.02 --router-latency=1 --link-latency=1  --link-width-bits=16 
--routing-algorithm=0
 Then, I built dsent using this command:
 python ./util/on-chip-network-power-area.py . m5out 
ext/dsent/configs/router.cfg ext/dsent/configs/electrical-link.cfg
 After that, it compiles dsent, but it gives this error:
 ("ERROR: Garnet network not used in '", './m5out/config.ini')
 To get past this error, I changed line 70 in on-chip-network-power-area.py from
 
 <unnamed.png&gt;
 
 to
 <unnamed_2.png&gt;
 
 But now I get the following error:
 Traceback (most recent call last):
 &nbsp; File "./util/on-chip-network-power-area.py", line 219, in <module&gt;
 &nbsp; &nbsp; main()
 &nbsp; File "./util/on-chip-network-power-area.py", line 216, in main
 &nbsp; &nbsp; buffers_per_control_vc, ni_flit_size_bits)
 &nbsp; File "./util/on-chip-network-power-area.py", line 161, in parseStats
 &nbsp; &nbsp; ["grep", pattern, stats_file]), '\n', -1)
 &nbsp; File "/usr/lib/python2.7/subprocess.py", line 223, in check_output
 &nbsp; &nbsp; raise CalledProcessError(retcode, cmd, output=output)
 subprocess.CalledProcessError: Command '['grep', 'sim_seconds', 
'./m5out/stats.txt']' returned non-zero exit status 1
 It seems that on-chip-network-power-area.py cannot parse the stats. What 
causes this error to happen and how can I fix it?
 
 
 Warm regards,
 Ali
