Reusing Compilation Results with clCreateProgramWithBinary

If 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 if this is true for your specific program and 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 calling
clCreateProgramWithBinary
. Another way to save intermediate binaries is to use the OpenCL Code builder, as described in the
User Manual - OpenCL™ Code Builder
.
Note
Intermediate representations are different for the CPU and the Intel® Graphics devices.

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.
