I thought mkl had support for multithreading SpMV, is it just lacking python bindings?</P><P>Thanks!</P><P>&nbsp;</P> Wed, 18 Sep 2019 15:38:09 GMT https://community.intel.com/t5/Intel-Distribution-for-Python/SpMV-multithreaded/m-p/1165025#M1241 marchesini__stefano 2019-09-18T15:38:09Z https://community.intel.com/t5/Intel-Distribution-for-Python/SpMV-multithreaded/m-p/1165026#M1242 <P>No, CSR's matvec&nbsp;<A href="https://github.com/scipy/scipy/blob/master/scipy/sparse/sparsetools/csr.h#L1122">is</A> sequential.&nbsp;sparse.mvecs <A href="https://github.com/scipy/scipy/blob/master/scipy/sparse/sparsetools/csr.h#L1158">uses</A> BLAS axpy, and is threaded across collection of vectors.</P> Fri, 20 Sep 2019 14:08:54 GMT https://community.intel.com/t5/Intel-Distribution-for-Python/SpMV-multithreaded/m-p/1165026#M1242 Oleksandr_P_Intel 2019-09-20T14:08:54Z
