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 ) |
