A random-access input wrapper for dereferencing array values through texture cache. Uses older Tesla/Fermi-style texture references.
ValueType*. References to elements are to be loaded through texture cache.UNIQUE_ID template parameter is used to statically name the underlying texture reference. Only one TexRefInputIteratorTinstance can be bound at any given time for a specific combination of (1) data type T, (2) UNIQUE_ID, (3) host thread, and (4) compilation .o unit.TexRefInputIteratorTto dereference a device array of doubles through texture cache. | T | The value type of this iterator |
| UNIQUE_ID | A globally-unique identifier (within the compilation unit) to name the underlying texture reference |
| OffsetT | The difference type of this iterator (Default: ptrdiff_t) |
