A set of functions that provide primitive cache control.
Global Functions
int dnnl::get_primitive_cache_capacity()Returns the number of primitives that can be held in the primitive cache at the same time.
void dnnl::set_primitive_cache_capacity(int capacity)Sets a number of primitives that can be held in the primitive cache at a time.
Parameters:
capacity |
Primitive cache capacity to set. If a new capacity is less than a number of primitives that the primitive cache already has then the excess entries will be evicted. Setting the capacity to 0 clears the primitive cache and disables it. Concurrently modifying capacity is safe. |
Returns:
dnnl_invalid_arguments / dnnl::status::invalid_arguments if the capacity value is invalid, and dnnl_success / dnnl::status::success on success.
dnnl_status_t DNNL_API dnnl_get_primitive_cache_capacity(int* capacity)Returns the number of primitives that can be held in the primitive cache at the same time.
Parameters:
capacity |
Primitive cache capacity to query. Concurrently accessing capacity is safe. |
Returns:
dnnl_invalid_arguments / dnnl::status::invalid_arguments if the capacity value is invalid, and dnnl_success / dnnl::status::success on success.
dnnl_status_t DNNL_API dnnl_set_primitive_cache_capacity(int capacity)Sets a number of primitives that can be held in the primitive cache at a time.
Parameters:
capacity |
Primitive cache capacity to set. If a new capacity is less than a number of primitives that the primitive cache already has then the excess entries will be evicted. Setting the capacity to 0 clears the primitive cache and disables it. Concurrently modifying capacity is safe. |
Returns:
dnnl_invalid_arguments / dnnl::status::invalid_arguments if the capacity value is invalid, and dnnl_success / dnnl::status::success on success.
