Library to calculate Distance Metrics on GPU Suggestions of widely used and fast GPU libraries that calculate the Euclidean distance of a vector from a matrix of vectors (of the same dimension) ?

Preferably one that works on NVIDIA GPUs.

Need it as a part of comparing solutions that evaluate Radial Basis Function Neural Networks.
If you are using python, use CUDA tool-kit with cudamat library. You will be able to perform matrix operations on GPU using cudamat.
