USDRT uses this information to mirror data between CPU and GPU when necessary, and to use the minimum number of CPU<->GPU copies when it does so. For example, if data is valid on CPU and is then requested on GPU with eOverwrite, USDRT doesn’t have to copy the data from CPU to GPU because it knows the GPU is about to overwrite it.
