sparse matrices/ sparse matrix multiplication algorithmsimple algorithmscalar processorsvector processorsphysics computingSummary: A simple algorithm for multiplication of sparse matrices is proposed. This algorithm can be easily incorporated into existing matrix multiplication routines. Behavior of the given ...
For m≤ n 1.68, the new algorithm is also faster than the best known matrix multiplication algorithm for dense matrices which uses O(n 2.38) algebraic operations. The new algorithm is obtained using a surprisingly straightforward combination of a simple combinatorial idea and existing fast ...

where A is a sparse matrix and C,B are dense matrices. I would like to have some details about the algorithm for sparse-dense matrix multiplication implemented by mkl_sparse_s_mm, i.e., if it uses cache aware strategies, specific micro-kernel implementations to fully leverage CPU registers...

This means that the current upperbounds by Yuster cannot be improved without improving the sparse matrix multiplication algorithm by Yuster and Zwick~(ACM TALG'05) and vice versa. 展开 关键词: Computer Science - Data Structures and Algorithms ...

The SEM model log-likelihood is not as amenable to the vectorized form, but can be solved using more conventional optimization, such as a simplex algorithm. Nonetheless, a grid of values for the log-determinant over the feasible range for λ can be used to speed evaluation of the log-...
