As I commented, the CUSP library is available for matrix multiplication. From the site:

Cusp is a library for sparse linear algebra and graph computations on CUDA. Cusp provides a flexible, high-level interface for manipulating sparse matrices and solving sparse linear systems.

The current version of cuSPARSE (CUDA Toolkit v5.0) supports sparse matrix-sparse matrix multiplications using the cusparse<t>csrgemm functions.

For this routine, compute capability 2.0 or better is needed.
