Reuse Compilation Results with clCreateProgramWithBinary

If the compilation time for an OpenCL™ program is of concern, consider reusing compilation results. It is typically faster than recreating you program from the source, but you should check for the specific program or device.
To retrieve binaries generated from calls to
clCreateProgramWithSource
 and
clBuildProgram
, you can call
clGetProgramInfo
 with the
CL_PROGRAM_BINARIES
 parameter. For the performance-critical applications that typically precompile kernel code to an Intermediate Representation (IR), you can cache the resulting binaries after the first OpenCL compilation and reuse them on subsequent executions by use of
clCreateProgramWithBinary
. Another way to save intermediate binaries is to use the Intel® SDK for OpenCL™ Applications, as described in the Developer Guide for Intel® SDK for OpenCL™ Applications.

Product and Performance Information

1

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.
