EU Occupancy - Shader Thread EU Occupancy

Metric Name
Description
EU Array: EU Thread Occupancy
Percentage of time that all EU threads were occupied with shader threads.
For GPGPU cases, when
EU Array: EU Thread Occupancy
is below 80 percent, it can indicate a dispatch issue (see the section on “Dispatch and Thread Occupancy” for tips on improving dispatch), and the kernel may need to be adjusted for more optimal dispatch.
For 3D cases, low occupancy means the EUs are starved of shader threads by a unit upstream of thread dispatch.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
