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

.
