Detailed Description

Class Documentation

struct cldnn_engine_configuration

Configuration parameters for created engine.

Definition at line 131 of file cldnn.h.

Class Members
const char *	compiler_options	OpenCL compiler options string.
uint32_t	dump_custom_program	dump the custom generated program to files
uint32_t	enable_parallelisation	Enables parallel execution of primitives which don't depend on each other. Disabled by default.
uint32_t	enable_profiling	Enable per-primitive profiling.
const char *	engine_log	Specifies a file to which engine log should be dumped. Null/empty values means no logging.
uint32_t	meaningful_kernels_names	Generate meaniful names fo OpenCL kernels.
uint32_t	priority_mode	Placeholder for priority mode (support of priority hints in command queue). Currently ignored.
const char *	single_kernel_name	If provided, runs specific layer.
const char *	sources_dumps_dir	Specifies a directory where sources of cldnn::program objects should be dumped. Null/empty values means no loggins.

struct cldnn_engine_info

uint64_t	max_local_mem_size	Maximum size of local memory arena in bytes.
uint64_t	max_work_group_size	Maximum number of work-items in a work-group executing a kernel using the data parallel execution model.
uint8_t	supports_fp16	Does engine support FP16.
uint8_t	supports_fp16_denorms	Does engine support denormalized FP16.
uint8_t	supports_subgroups_short	Does engine support cl_intel_subgroups_short.

Defines available engine types.
