Does mkl_sparse_sp2m support multithreading or not?

[miaodi1987]

Hi,

I am a new user of MKL library. I mainly use MKL via PETSc function calls. I found that dense matrix multiplication (cblas_dgemm) is multithreaded. However, when I run sparse matrix multiplication (mkl_sparse_sp2m) I only see that it is running in serial mode. Could I know if mkl_sparse_sp2m supports multithreading? 

And how should I know if a function in mkl supports multithreading or not?

Thank you!
