Avoid Needless Synchronization

For best results, try to avoid explicit command synchronization primitives, such as clEnqueueMarker/Barrier. Explicit synchronization commands and event tracking result in cross-module round trips, which decrease performance. The less you use explicit synchronization commands, the better the performance.

Use the following techniques to reduce explicit synchronization:

Optimization Notice

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.
