Detailed Description

Simple C++ example to show how run a kernel with assert*() and PRINT*() macros and test them.

Definition in file example.cpp.

Function Documentation

◆ dirname()

std::string dirname ( std::string path )

Return the directory part of path.

Definition at line 224 of file example.cpp.

◆ error_name()

std::string error_name ( cl_int code )

Return the error name corresponding to the error code.

Definition at line 177 of file example.cpp.

◆ file_to_string()

std::string file_to_string ( std::string filename )

Read the file and return its content to a string. If failed then print a error message and exit.

Definition at line 187 of file example.cpp.

◆ get_device()

cl::Device get_device	(	unsigned int	platform_i,
		unsigned int	device_i
	)

Return the given device of the given platform OpenCL, or exit if doesn't exists.

Parameters

platform_i
device_i

Returns: OpenCL device

Definition at line 204 of file example.cpp.

◆ main()

int main	(	int	argc,
		const char *const	argv[]
	)

Get the optional parameter –device platform:device and run the kernel ../kernel/example.cl.

Definition at line 398 of file example.cpp.

◆ print_error()

void print_error	(	cl_int	code,
		std::string	message = `""`
	)

If code != 0 then print an error message corresponding to the error code.

Definition at line 241 of file example.cpp.

◆ run_example()

void run_example	(	unsigned int	nb_work_group,
		unsigned int	nb_work_items_by_work_group,
		cl::Device	device,
		bool	debug,
		const std::string &	path
	)

Run the kernel ../kernel/example.cl.

If debug then run the kernel in debug mode, else run the kernel with the macro NDEBUG defined.

Definition at line 257 of file example.cpp.

Variable Documentation

◆ errors_map

const std::map<int32_t, std::string> errors_map

List of all error codes and names extracted from /usr/include/CL/cl.h.

Definition at line 35 of file example.cpp.
