Re: [Gems-users] Injection rate option doesn't work

[Niket Agarwal <niketa@xxxxxxxxxxxxx>]

Hi Minneong, 

What you are seeing is "Average network latency" and it is the number of cycles that a flit spends in the network. At saturation, this does not increase and what increases is the queuing delay at network interfaces. In the printStats function in GarnetNetwork_d.C, please uncomment the lines that print out the queuing latency and total latency to see those values.

Hi Niket,

 

I am using Garnet network-tester at http://www.princeton.edu/~niketa/garnet_files/tester-network-only.tgz

 

I wanted to get “injection rate – average latency” curve which is in the GARNET technical paper,

However, injection rate option (‘-i’ parameter) in the network-tester doesn’t work at all.

 

I checked the “Tester.C” file and injection_rate was just set to 0.1.

However, even if I change the injection_rate value, Average network latency never increased over 100.

And I don’t see any similarity between my result and the curve in the paper.

 

Is there anything I did wrong?

lease help me doing this.

 

Thank you.
