Detailed Description

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

Parameters

[in]	x_cb	Checkerboarded space-time index we are requesting
[in]	parity	Parity we are requesting
[in]	chirality	Chirality we are requesting

Returns: Instance of a colorspinor_wrapper that curries in access to this field at the above coordinates.
