walberla::gpu::FieldIndexing< T > Class Template Reference

Detailed Description

template<typename T>
class walberla::gpu::FieldIndexing< T >

Utility class to generate handles to the underlying device data of a GPUField.

Pre-calculate memory offsets of a GPUField for a given slice, cell interval, or the entire grid with or without the ghost layer, and store them in a FieldAccessor handle. That handle is obtained by calling gpuAccess().

#include <FieldIndexing.h>
