NCU

[Giant Hand]

I understand that the average_usage.cpus value in the cluster data represents NCU.
Since NCU is a normalized compute unit, shouldn't its values be confined to the 0–1 range when expressed as a percentage?
However, I noticed that some values exceed 1 (for example 65.5), and I would like to understand why this occurs.

Additionally, I would like to use the average_usage.cpus values as non-normalized (absolute) compute usage values rather than normalized percentages.
Is this possible? If so, how can I retrieve or calculate the unnormalized values?

I would appreciate your clarification on these points.

Cheers,

Hi.

From the documentation: "Normalized Compute Units, or NCUs ... values will be in the range [0,1]."  There's always a bit of noise in large-scale traces like this, but I would be surprised if there were a lot of values > 1.0  (these are fractions, not percentages!)  Do you see a large number of such values?

We do not provide information on how to denormalize the values.  (See the section on Obfuscation techniques in the documentation.)

Best,
