[ViennaCL-devel] Paper on an improved Sparse Matrix Format..

[Philippe T. <phi...@gm...>]

Hello,

Just to share this paper which I have not had the time to read :

arxiv.org/pdf/1203.5737.pdf

Abstract:

We present new format for storing sparse matrices on GPU. We compare it
with several other formats including CUSPARSE which is today probably the
best choice for processing of sparse matrices on GPU in CUDA. Contrary to
CUSPARSE which works with common CSR format, our new format requires
conversion. However, multiplication of sparse-matrix and vector is
significantly faster for many matrices. We demonstrate it on set of 1 600
matrices and we show for what types of matrices our format is profitable.
