Detailed Description

Function Documentation

hemmA()

template<Target target, typename scalar_t >

void slate::impl::hemmA	(	Side	side,
		scalar_t	alpha,
		HermitianMatrix< scalar_t >	A,
		Matrix< scalar_t >	B,
		scalar_t	beta,
		Matrix< scalar_t >	C,
		Options const &	opts
	)

Distributed parallel Hermitian matrix-matrix multiplication. Generic implementation for any target. Dependencies enforce the following behavior:

• bcast communications are serialized,
• hemm operations are serialized,
• bcasts can get ahead of hemms by the value of lookahead. Note A, B, and C are passed by value, so we can transpose if needed (for side = right) without affecting caller.

ColMajor layout is assumed

hemmC()

template<Target target, typename scalar_t >

void slate::impl::hemmC	(	Side	side,
		scalar_t	alpha,
		HermitianMatrix< scalar_t >	A,
		Matrix< scalar_t >	B,
		scalar_t	beta,
		Matrix< scalar_t >	C,
