Description

As discussed in Slack, I will make below changes of resources presentation in YuniKorn UI.

1. Chang memory unit to binary-based. For example: 'kB', 'MB', 'GB', 'TB', 'PB’→’Ki’, ‘Mi’, ‘Gi’, ‘Ti’, ‘Pi’
2. Align CPU unit with K8S, remove ‘k’ from CPU unit and use ‘m’ to present millicpu. For example: 1000 → 1000m, 10k → 10
3. Change the fixed digit number from 1 to 2

 

Record the motivations here:

• Regarding Memory unit, the primary motivation is that most resource monitoring systems are using binary-based. For instance, in the K8S Dashboard, the node capacity is displayed as 30.98Gi, while in the YuniKorn UI, it shows as 33.3 GB. Without a calculator, comparing these values becomes challenging.
• Regarding CPU unit, the motivation is to align with K8S
• Regarding the fixed digit number change. Consider this scenario, if I sumitted a job with 1000Mi memory, the current UI show 1.0 GB memory allocated. However, the true value is 1.048576 GB. Change to 2 fixed digits is more accuracy.

Attached the proposed result after changing.
