Best General Sparse Matrix Library?

Accelerated Computing GPU-Accelerated Libraries

There are a couple of sparse matrix libraries for CUDA - one is NVIDIA’s CUSPARSE library and the other is EM Photonics’ CULA|Sparse library. Will NVIDIA’s sparse lib superseed EM Photonics’ library or the other way around? Also, the reference documentation for NVIDIA’s sparse library is lacking - is that because NVIDIA has stopped development? Or is everybody now using Magma Sparse?

Which is the best general sparse lib for CUDA devices?

Can you give an example for how the reference documentation for NVIDIA’s sparse library (i.e. CUSPARSE) is lacking? I’m not disputing the statement, just curious. I assume you’re aware of the documentation here:
