Detailed Description

template<typename ElementOutput_, int Count, typename ElementAccumulator_ = ElementOutput_, typename ElementCompute_ = ElementOutput_, FloatRoundStyle Round = FloatRoundStyle::round_to_nearest> class cutlass::epilogue::thread::LinearCombinationClamp< ElementOutput_, Count, ElementAccumulator_, ElementCompute_, Round >

Applies a linear combination operator to an array of elements then clamps the output before converting to the output element type.

D = alpha * accumulator + beta * source + uniform
