herk()

template<Target target, typename scalar_t >

void slate::impl::herk	(	blas::real_type< scalar_t >	alpha,
		Matrix< scalar_t >	A,
		blas::real_type< scalar_t >	beta,
		HermitianMatrix< scalar_t >	C,
		Options const &	opts
	)

Distributed parallel Hermitian rank k update. Generic implementation for any target. Dependencies enforce the following behavior:

• bcast communications are serialized,
• herk operations are serialized,
• bcasts can get ahead of herks by the value of lookahead. Note A and C are passed by value, so we can transpose if needed (for uplo = Upper) without affecting caller.
