Detailed Description

template<typename Float, int length, int N, bool add_rho = false, bool huge_alloc = false>
struct quda::clover::FloatNOrder< Float, length, N, add_rho, huge_alloc >

Accessor routine for CloverFields in native field order.

Template Parameters

Float	Underlying storage data type of the field
length	Total number of elements per packed clover matrix (e.g., 72)
N	Number of real numbers per short vector
add_rho	Whether to add the constant rho onto the diagonal. This is used to enable Hasenbusch mass preconditioning.
huge_alloc	Template parameter that enables 64-bit pointer arithmetic for huge allocations (e.g., packed set of vectors). Default is to use 32-bit pointer arithmetic.
