Hi Al, thank you for the response!
Do you think that this problem is a flaw in the DCMI implementation of the current motherboard firmware? In this case, we could hope it is to be corrected in future versions. Or is it rather a policy of the vendor? It seems so since they don’t provide the raw command for PSU monitoring. Are we to abandon plans for using freeipmi-based accounting in SLURM for this cluster?
