Computing Threads Started

Metric Description

Number of threads started across all EUs for compute work.

Possible Issues

High thread issue rate lowers GPU usage efficiency due to thread creation overhead even for lightweight GPU threads. To improve performance, change the kernel code to increase the load in a working item, adjust global working size, and so decrease the number of GPU threads.
