conso_sensor: Evaluate the power consumption

Closed this issue · 1 comments

da-ekchajzer commented

Problem

For each workload, we need to collect the power consumption of the components or the machine.

Solution

We need to take into account multiple sources of consumption data to address the maximum architecture and compare the data sources between them.

  • RAPL
  • IMPI
  • MANUAL

This feature should be done in boagent. See : Boavizta/boagent#35

Informations

RAPL

We can either access directly to RAPL API (https://web.eece.maine.edu/~vweaver/projects/rapl/) or access it through another software such as scaphandre (https://github.com/hubblo-org/scaphandre)

Intel

For RAM and CPU, we can use RAPL

AMD

According to @bpetit, RAPL should work for AMD x86, with Linux core 5.11 or higher

ARM

RAM

Discussion in progress hubblo-org/scaphandre#35

IPMI

Access the electrical evaluation through the IPMI API.

Manual

User should be able to provide the power consumption manually when they use a power sensor that is not implemented in Energizta (with external wattmeter for instance).

@bpetit I would be interested to have your opinion on that and maybe link it with ongoing issues in scaphandre

We should have a look to https://github.com/green-coding-berlin/tools and synchronize with green coding
