Matrix multiplication accelerationConvolutionLSTMIn this paper, we present hardware accelerators created with high-level synthesis techniques for sparse and dense matrix multiplication operations. The cores can operate with different precisions and are designed to be integrated in a heterogeneous CPU-FPGA ...
Sparse-matrix dense-matrix multiplication (SpMM) is a fundamental linear algebra operation and a building block for more complex algorithms such as finding the solutions of linear systems, computing eigenvalues through the preconditioned conjugate gradient, and multiple right-hand sides Krylov s...
Problem: C = A * B + C , where A is dense and B is sparse. I know that I can use "mkl_?csrmm" after taking the transpose of both matrices A and B but the transpose operation will be costly. Is there a better way or existing routine for dense-sparse...
def sddmm(A: SparseMatrix, X1: torch.Tensor, X2: torch.Tensor) -> SparseMatrix: r"""Sampled-Dense-Dense Matrix Multiplication (SDDMM). ``sddmm`` matrix-multiplies two dense matrices :attr:`X1` and :attr:`X2`, then elementwise-multiplies the result with sparse matrix :attr:`A` ...
class scipy.sparse.bsr_matrix(arg1, shape=None, dtype=None, copy=False, blocksize=None) The Block Compressed Row (BSR) format is very similar to the Compressed Sparse Row (CSR) format. BSR is appropriate for sparse matrices with dense sub matrices like the last example below. Block matrices...

There is support far a number of different sparse formats including ...
The combination of several software techniques (loop unrolling, software pipelining) together with blocking to the sparse matrix by dense matrix multiplication introduces a very large search space. Chapter 1 Introduction Todays high performance computers combine superscalar and/or superpipelined CPUs with....
Sparse Dense Matrix Multiplication torch_sparse.spmm(index, value, m, n, matrix) -> torch.Tensor Matrix product of a sparse matrix with a dense matrix. Parameters index(LongTensor)- The index tensor of sparse matrix. value(Tensor)- The value tensor of sparse matrix. ...
matrix multiplications with sparse data. One particularly effective method is the row-wise approach, also referred to as Gustavson’s algorithm, which has demonstrated high efficiency in calculating the matrix product A × B. The product of the matrix multiplication is produced row-wise, as follows...
In particular, we aim for an algorithm that becomes equal to the known optimal algorithms for the dense matrix multiplication in the case of a sparse matrix with 100% occupation. In particular, all-to-all communication is avoided in that case, too. Furthermore, a cache-oblivious strategy is...
