Notes 
Matrices used by S. Williams et al for sparse matrix multiplication on GPUs.   
                                                                               
14 matrices were used in the following paper:

Six of the matrices are nearly identical to the matrices already in the        
UF Collection.  They are thus not included in the UF Collection.  See          
the README.txt file for this collection for details.
