// the cache
// 2. scratchpad_t - a memory for scratchpad
// 3. primitive_desc_iface_t - an alias for dnnl_primitive_desc and is
// a user facing primitive descriptor (the one a user should create prior
// creating a primitive)
// 4. resource_mapper_t - a resource mapper that provides a mapping between
// impl::primitive_t and its resource
