Compute Active

This counter shows the percentage of time that Compute tasks were active.

It is worth noting that this counter is effectively a Boolean value that shows this processing stage as either active or idle. The counter is best used to graph activity over a long period of time. In small periods, the counter value will match the activity of Compute task timing data.

A high value indicates that Compute tasks have been active for a significant percentage of time. If you believe this is a bottleneck, you should reduce the complexity of your compute kernels and/or reduce the number of kernels executed.
