Spase by dense matrix product


#1

Can I ask if someone knows about sparse blas for Julia? I am particularly looking for multiplication of sparse and dense matrix? I have tried MKLSparse and https://github.com/dcjones/RecursiveSparseBlocks.jl. I am not sure I have invoked MKLSparse correctly. The RecursiveSparseBlocks is slower in my use-case. Any ideas are welcome. Size of my sparse matrix is abour 2000x150000 with average number of non-zero elements 0.5%, the dense matrix is abou 2000 by 40.

Thanks for answers.
