A new matrix storage is proposed for Computational Fluid Dynamics in Finite Elements.The main idea is to store assembled matrices in an Element By Element (EBE) way.This storage optimizes the memory required and speeds up the classical EBE matrix-vector product, but also enables to perform a ...
The vector–matrix product uT ⋅ B: = fB(u) = rowsum ∘ hB(u). Since matrix multiplication A ⋅ B is a sequence of fB(ai) computations, one for each row of A, one can apply a mantissa-based integer row checksum test to the hB (ai) components to precisely check for errors ...
SGEMV and DGEMV compute the matrix-vector product for either a real general matrix or its transpose, using the scalars α and β, vectors x and y, and matrix A or its transpose: y← β y+α Ax y ← βy+α ATx CGEMV and Z...

The matrix–vector product kernel can represent most of the computation in a gradient iterative solver. Thus, an efficient solver requires that the matrix–vector product kernel be fast. We show that standard approaches with Fortran or C may not deliver good performance and present a strategy invo...

The sparse matrix vector product (SpMV) is a key operation in engineering and scientific computing and, hence, it has been subjected to intense research for a long time. The irregular computations involved in SpMV make its optimization challenging. Therefore, enormous effort has been devoted to de...
