OpenCL Multi-Watch Views

This view lets you compare the values of an OpenCL Kernel variable across work-items and work-groups.

Variable Values

The Multiwatch main window displays either a graphical (image view) or spreadsheet (data view) visualization of the selected kernel variable across the various work-items and work-groups. This view operates very similarly to the Object views. The two following screenshots display a multi watch view for the kernel variable sum.s2. The upper screenshot shows an image view, the lower shows a data view.

Variable Name Combo-box

Select a variable name from the list, or type a watch expression. If the expression can be parse and evaluated, the values are updated in the main view.

Kernel Work Geometry and Selected / Hovered Details

Selecting, or hovering with the cursor over, work-items displays the kernel work geometry (local and global work size and offset) for the current N-dimensional kernel execution, as well as their location and value.

Value Range Slider

Shows the value range, and allows marking the valid value range. Values above and below these lines are colored to show they are not in the selected range.
