dpctl.program¶

Data Parallel Control Program

dpctl.program module provides a way to create a SYCL kernel from either a source string or SPIR-V binary file.

Classes¶

class dpctl.program.SyclKernel¶

addressof_ref()¶

Returns the address of the C API DPCTLSyclKernelRef pointer as a size_t.

Returns: The address of the DPCTLSyclKernelRef object used to create this SyclKernel cast to a size_t.

get_function_name()¶: Returns the name of the Kernel function.

get_num_args()¶: Returns the number of arguments for this kernel function.

class dpctl.program.SyclProgram¶

Wraps a sycl::program object created from an OpenCL interoperability program.

SyclProgram exposes the C API from dpctl_sycl_program_interface.h. A SyclProgram can be created from either a source string or a SPIR-V binary file.

addressof_ref()¶

Returns the address of the C API DPCTLSyclProgramRef pointer as a long.

Returns: The address of the DPCTLSyclProgramRef object used to create this SyclProgram cast to a long.

get_sycl_kernel()¶

has_sycl_kernel()¶

Exceptions¶

exception dpctl.program.SyclProgramCompilationError¶: This exception is raised when a SYCL program could not be built from either a SPIR-V binary file or a string source.

Functions¶

dpctl.program.create_program_from_source()¶

Creates a Sycl interoperability program from an OpenCL source string.

We use the DPCTLProgram_CreateFromOCLSource() C API function to create a Sycl progrma from an OpenCL source program that can contain multiple kernels. Note currently only supported for OpenCL.

Parameters

q (SyclQueue) – The SyclQueue for which the SyclProgram is going to be built.
src (unicode) – Source string for an OpenCL program.
copts (unicode) – Optional compilation flags that will be used when compiling the program.

Returns

A SyclProgram object wrapping the sycl::program returned by the C API.

Return type

program (SyclProgram)

Raises

SyclProgramCompilationError – If a SYCL program could not be created.

dpctl.program.create_program_from_spirv()¶

Creates a Sycl interoperability program from an SPIR-V binary.

We use the DPCTLProgram_CreateFromOCLSpirv() C API function to create a Sycl progrma from an compiled SPIR-V binary file.
