SpMV multithreaded?

[marchesini__stefano]

is the sparse matrix vector multiply multithreaded? 

Maybe I am doing something wrong, but I installed intel-python, intel-scipy and could not get multithreading for the SpMV (sparse matrix vector multiply) with sparse matrix in csr format, is it supported? I thought mkl had support for multithreading SpMV, is it just lacking python bindings?

Thanks!

No, CSR's matvec is sequential. sparse.mvecs uses BLAS axpy, and is threaded across collection of vectors.
