One of the earliest architectural design decisions that went into the CUDA platform for NVIDIA GPUs was support for backward compatibility of GPU code. This design means that new GPUs should be able to run programs written for previous GPUs without modification. It’s accomplished by two foundational features of CUDA: NVIDIA Parallel Thread Execution (PTX)…
