@component Roofline Model Plot based on uPlot
|
||||
|
||||
Properties:
|
||||
- `data [null, [], []]`: Roofline Data Structure, see below for details [Default: null]
|
||||
- `renderTime Bool?`: If time information should be rendered as colored dots [Default: false]
|
||||
- `allowSizeChange Bool?`: If dimensions of rendered plot can change [Default: false]
|
||||
- `subCluster GraphQL.SubCluster?`: SubCluster Object; contains required topology information [Default: null]
|
||||
- `width Number?`: Plot width (reactively adaptive) [Default: 600]
|
||||
- `height Number?`: Plot height (reactively adaptive) [Default: 380]
|
||||
|
||||
Data Format:
|
||||
- `data = [null, [], []]`
|
||||
- Index 0: null-axis required for scatter
|
||||
- Index 1: Array of XY-Arrays for Scatter
|
||||
- Index 2: Optional Time Info
|
||||
- `data[1][0] = [100, 200, 500, ...]`
|
||||
- X Axis: Intensity (Vals up to clusters' flopRateScalar value)
|
||||
- `data[1][1] = [1000, 2000, 1500, ...]`
|
||||
- Y Axis: Performance (Vals up to clusters' flopRateSimd value)
|
||||
- `data[2] = [0.1, 0.15, 0.2, ...]`
|
||||
- Color Code: Time Information (Floats from 0 to 1) (Optional)
