Lack of *cscmv functions in ARM performance library

Hi,

Yes, Arm Performance Libraries have a lot of sparse linear algebra functionality, including the sparse matrix-vector multiplication functionality you mention.  However the interface is slightly different to that in oneMKL.  Indeed the functions you reference are themselves deprecated.  All vendor libraries have moved towards an "inspector-executor" model of operation which means that there is much greater opportunity for optimization and hence increased performance for you.

For a description of exactly how this works in Arm Performance Libraries have a read of https://developer.arm.com/documentation/101004/2410/Sparse-Linear-Algebra/Sparse-Linear-Algebra-Introduction and look at the example that follows.  The example is in CSR format, rather than CSC, but both are supported in ArmPL, along with other sparse matrix formats.

Hope this helps.

Thanks for your comments. I understood your idea to refine our codes to adopt the 'inspector-executor' model of operations. 

We will consider and try.
