<p>Cactus supports CUDA programming in the option lists level via various <code>CUDA_FOO</code> variables but does not provide macros for <code>__device__</code> and <code>__host__</code> modifiers used by both CUDA and HIP accelerators.</p>
<p>It would be good if Cactus could provide those depending on which compiler is detected, Predefined defines to look for are (copying AMReX): <code>CUDA_ARCH || HIP_DEVICE_COMPILE || SYCL_DEVICE_ONLY</code> (in its <code>include/AMReX_GpuQualifiers.H</code>).</p>
