Comparing CuPy to NumPy and CUDA
Let's compare CuPy to NumPy and CUDA in terms of simplicity in parallelization. In the following table, we explore the scope of CuPy with respect to NumPy and CUDA so as to understand the scenarios when CuPy could be advantageous to both. Here are some of the differences:
|
CUDA |
NumPy |
