Hi everyone,
(regarding the list, the home page is https://lists.netdevconf.info/postorius/lists/net-power.netdevconf.info/)
I think we don't have a lot of subscribers yet to this list (hey Jamal you should subscribe!) - invite your power-concerned friends and colleagues.
Toke and I were chatting offline about this problem of power management in networking.
We thought it might be a useful start to figure out a good set of benchmarks to demonstrate "power vs networking" problems. I have a couple in mind right away. One is "system is sleeping but I'm trying to run a latency sensitive workload and the latency sucks" Two is "system is sleeping and my single-threaded bulk throughput benchmark (netperf/iperf2/neper/etc) shows a lot of retransmits and / or receiver drops"
Another thought is how do I count these events and / or notice I have a problem?
More thoughts on this from anyone?

There was an interesting talk in Kubecon about power management:

Apparently the HPC guys have been thinking about this problem for quite
some time. There's a tool from Intel (hey Jesse!) called GEOPM that can
model power consumption and be used to forecast the tradeoffs!
With these AI farms getting bigger and bigger, seems like a lot from HPC
can be applied here.
