sparse matrix multiplication program openmp

I'm looking for any standard C program that uses OpenMP APIs for a sparse matrix-vector or matrix-matrix multiplications. Can anyone let m开发者_如何学Goe know if there are any such programs.

If you are not looking for an open-source library, you can try to have a look at the Intel MKL Sparse-BLAS level 2 and level 3 routines:

These libraries should be multithreaded using OpenMP, as stated in the following page:

I don't understand why you are looking for a 3rd party library to perform sparse matrix-matrix multiplications.

Have a look at this great Book (Introduction to Parallel Computing): http://www.scribd.com/doc/60118054/72/The-matrix%E2%80%93vector-multiplication-with-OpenMP
