Unleash Intel® Advanced Vector Extensions 512 Inside the Open Shading Language


Intel joined forces with Pixar Animation Studios* and Sony Pictures Imageworks* to realize a dynamic Single Instruction Multiple Data (SIMD) code generation of open shading language (OSL) shader networks and an expanse of SIMD optimized OSL library functions. Discover our new “wide” batch OSL interface that handles LLVM vector types, masks control flow, and creates library functions (achieving three to nine times the speed up with Intel® Advanced Vector Extensions 512) using compiler driven SIMD optimization (no intrinsics) with OpenMP*.



Product and Performance Information


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.
