Hi,
One of the requests from the scheduler maintainers at the Energy-aware Scheduling workshop at Kernel Summit this year was to provide plain text descriptions of use-cases (workloads) and system topologies. To get that moving I have written some short texts about some use-cases. In addition I described a list of issues that today prevent mainly the scheduler from achieving a good energy/performance balance in common use-cases. The follow-up emails are structured as follows:
1-6: Current issues related to energy/performance balance. 7-10: Use-cases (overall behaviour and energy/performance goals) 11: DVFS example (for reference)
I'm hoping that this provides some of the background for why I'm interested in improving energy-awareness in the scheduler. I'm aware that the use-cases and issues/wishlist don't cover everyone's area of interest. Input is needed to fix that.
Comments and input are appreciated.
Morten
