-------------------------------------
Summary: Improve presentation of resource units in YuniKorn UI
Key: YUNIKORN-2140
URL: https://issues.apache.org/jira/browse/YUNIKORN-2140
Project: Apache YuniKorn
Issue Type: Improvement
Components: webapp
Reporter: Yu-Lin Chen
Assignee: Yu-Lin Chen
Attachments: YuniKorn UI Units.png
As discussed in Slack, I will make below changes of resources presentation in
YuniKorn UI.
# Chang memory unit to binary-based. For example: 'kB', 'MB', 'GB', 'TB',
'PB’→’Ki’, ‘Mi’, ‘Gi’, ‘Ti’, ‘Pi’
# Align CPU unit with K8S, remove ‘k’ from CPU unit and use ‘m’ to present
millicpu. For example: 1000 → 1000m, 10k → 10
# 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.
