devPtr
DevPtr is a term commonly used in the context of programming, particularly in languages like C and C++. It stands for "device pointer" and is a type of pointer used in CUDA (Compute Unified Device Architecture), a parallel computing platform and application programming interface (API) model created by NVIDIA. CUDA allows developers to use NVIDIA GPUs for general purpose processing, an approach known as GPGPU (General-Purpose computing on Graphics Processing Units).
A device pointer is a pointer that points to memory allocated on the GPU (Graphics Processing Unit).
In CUDA programming, developers often use the keyword __device__ to declare device functions and variables that
Proper management of device pointers is essential for efficient GPU programming. This includes allocating and deallocating
