Re: [Freeipmi-users] Power statistics for Supermicro A+ 1023US-TR4 server

[Vladimir Stegailov]

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?
