EU Array Stalled

Metric Description

The normalized sum of all cycles on all cores spent stalled. At least one thread is loaded, but the core is stalled for some reason.

Possible Issues

A significant portion of GPU time is spent in stalls. For compute bound code it indicates that the performance might be limited by memory or sampler accesses.
