* \par Overview
* The [<em>SpMV computation</em>](http://en.wikipedia.org/wiki/Sparse_matrix-vector_multiplication)
* performs the matrix-vector operation
* <em>y</em> = <em>alpha</em>*<b>A</b>*<em>x</em> + <em>beta</em>*<em>y</em>,
* <em>y</em> = <b>A</b>*<em>x</em> + <em>y</em>,
* where:
* - <b>A</b> is an <em>m</em>x<em>n</em> sparse matrix whose non-zero structure is specified in
* [<em>compressed-storage-row (CSR) format</em>](http://en.wikipedia.org/wiki/Sparse_matrix#Compressed_row_Storage_.28CRS_or_CSR.29)
* (i.e., three arrays: <em>values</em>, <em>row_offsets</em>, and <em>column_indices</em>)
* - <em>x</em> and <em>y</em> are dense vectors
* - <em>alpha</em> and <em>beta</em> are scalar multiplicands
