Given an AMD on 64-bit Linux environment what is the best way to work with sparse matrices? I hunted through the AMD Core Math Library but I didn't see support for a sparse matrix. I found the documentation for "3 BLAS: Basic Linear Algebra Subprograms" at http://developer.amd.com/cpu/Libraries/acml/onlinehelp/Documents/BLAS.html#index-sparse-BLAS-47 which reads:
"ACML also includes interfaces to the extensions to Level 1 BLAS known as the sparse BLAS. These routines perform operations on a sparse vector x which is stored in compressed form and a vector y in full storage form. See reference  for more information."
So it would seem that ACML supports sparse vectors but not sparse matrices. If this is the case can someone recommend an alternative library?
