Can MKL perform matrix-vector multiply or matrix-matrix multiply for sparse matrix in variable block row (vbr) format?

rdees — Tue, 01 Jun 2010 15:09:56 GMT

I have a matrix, in sparse, variable block row format, (i.e. vbr) that I need to use the MKL to operate on. Since the off diagonal blocks are not square, Ibelieve that I cannotuse the block sparse row(bsr) that is providedin MKL.

1. Is there a way around this? That is, can Isomehow 'dummy up' the matricesso that I can use MKL?

2. Is my only choice to use the National Institute of Standards, NIST "vbr" subroutines?

3.Are there plans to include the "vbr" format into MKL?

Many thanks for you help.
Bob

Bob,

1)there is no way to do this in the current versions

2) yes, these routines will be able to help you
