We focus on the design of kernels for sparse matrix-vector multiplication. Although CUDA kernels may be compiled into sequential code that can be run on any architecture supported by a C compiler, our SpMV kernels are designed to be run on throughput-oriented architectures in general and the ...
An important kernel of scientific software is the multiplication of a sparse matrix by a vector. The efficiency of the algorithm on a vector computer depends on the storage scheme. With a storage by rows, performances are limited in general by the small vector length. Therefore a storage by ...
I believe the sparse matrix code is implemented by a few specialized TMW engineers rather than an external library like BLAS/LAPACK/LINPACK/etc. So it will be quite a bit of work for them, but you never know... Send them flowers, candy, etc!! :)
🚀 The feature, motivation and pitch I want to do a sort of batched sparse-sparse matrix multiplication, but specifically in the scenario where I have two hybrid sparse coo tensors of the shape (N,N,C), where only the C dimension is a den...
Computational Aspects of GPU-accelerated Sparse Matrix-Vector Multiplication for Solving Markov Models In this article we investigate some computational aspects of GPU-accelerated matrix-vector multiplication where matrix is sparse. Particularly, we deal wit... B Bylina,J Bylina,M Karwacki - 《Theoreti...
2.5 Matrix Multiplication Matrix multiplication does not mean multiplying term by term; it is not an array operation. Matrix multiplication has a very specific meaning. First of all, to multiply a matrix A by a matrix B to result in a matrix C, the number of columns of A must be the sa...
