I need to perform a multiplication between two fairly large sparse matrices C = A * B and I would like to try using the GPU for that. The problem arises in a context where A represents a fixed 2D convolution kernel, while B represents a list of 2D images (each of which is a column of B). Therefore, …

Thank you @gdalle. I had a look and could only find matrix-vector kernels, but perhaps I am missing something.
