SMX

Configuration

This compute unit implements the Kepler architecture. It consists of a single block with the following execution units. Additionally, this compute unit has multiple issue ports. Instructions scheduled onto separate issue ports can execute in parallel, but they require some instruction-level parallelism in the input.

Data type	Issue port	Execution rate
FP32	0, 1, 2, 3, 4, 5	32 lanes, executing one operation per cycle
INT32	0, 1, 2, 3, 4, 5	32 lanes, executing one operation per cycle
FP64	6	8 lanes, executing one operation per cycle
