Description

Declares helper functionality for device transfers for tests for GPU host allocator.

Undefined symbols in Google Test, GROMACS use of -Wundef, and the implementation of FindCUDA.cmake and/or nvcc mean that no compilation unit should include a gtest header while being compiled by nvcc. None of -isystem, -Wno-undef, nor the pragma GCC diagnostic work.

Thus, this header isolates CUDA-specific functionality to its own translation unit. The OpenCL and no-GPU implementations do not require this separation, but do so for consistency.
