Hi everybody

I am new in gem5 and I have a question. How can calculate request injection
rate from stats of gem5 with garnet2?

Thank you

The stats.txt file lists the packet injection rate when u run any design with garnet2.0

Cheers,

Dear All,

I like to add one more question within this issue. I like to know how much clock cycle is required for the neighbor node to send the complete packet i.e. Node 0 to node 1 in mesh connection in garnet 2.0. In this case, if the packet requires to wait infinite time, then can we check which packet is taking long time?

Thanks a lot.

Hi Tushar


yes I saw the packet and flit injection like bellow in my stas.txt:


system.ruby.network.packets_injected | 0 0.00%
0.00% | 0 0.00% 0.00% | 88805 0.78%
0.78% | 5593156 49.00% 49.77% | 5652975 49.52%
99.29% | 80676 0.71% 100.00%
system.ruby.network.packets_injected::total 11415612

system.ruby.network.flits_injected | 0 0.00%
0.00% | 0 0.00% 0.00% | 88805 0.75%
0.75% | 5593156 47.52% 48.27% | 6008115 51.04%
99.31% | 80676 0.69% 100.00%
system.ruby.network.flits_injected::total 11770752

but these are not injection rate? how can I calculate rate of that?

and what are the values in bellow? why It has multiple value?

system.ruby.network.packets_injected | 0 0.00%
0.00% | 0 0.00% 0.00% | 88805 0.78%
0.78% | 5593156 49.00% 49.77% | 5652975 49.52%
99.29% | 80676 0.71% 100.00%


thanks

For avg rate just divide total packets injected by total cycles (sim_ticks)

Different values are per virtual network. Their sum will add up to the total.

Thank you Tushar

does it need to convert tick to clock cycle?

and I have another elementary question too.

how can I compare stats.txt of two designs? with which stats I can understand
the improvement of performance ?


Thanks.
