Detailed Description

template<typename inType = double, typename outType = double>
struct exahype2::CopyCellDataGPU< inType, outType >

Cousing to CellData which administers copies on the accelerator.

This is a variant of CellData which also present GPU data. However, this flavour copies all data manually onto the GPU, whereas its parent is a proxy around data. As we copy data over, we can also rearrange all data. From a user point of view, the big difference is that we have to invoke copyBackAndDestroy() manually to eliminate the data on the device:

Copies to the device occur automatically on construction, but copies back must be triggered manually using copyBackAndDestroy().

The OpenMP implementation offers two versions, one using allocations on the device, and another that keeps data on the host. This second version requires explicit maps in the kernel, which do not currently exist. For this reason it is currently not in use.
