We present parallel and sequential dense QR factorization algorithms that are both optimal (up to polylogarithmic factors) in the amount of communication they perform, and just as stable ...SVD: For an SVD on the small matrix B on the GPU, we compared gesvd() routines provided by MAGMA and cuSOLVER library and found that there were not much performance difference in terms of both speed and accuracy. We therefore chose cuSOLVER included in the CUDA library to keep the implementation simple and portable.The implementation of torch.linalg.svd () on CPU uses LAPACK's routine ?gesdd (a divide-and-conquer algorithm) instead of ?gesvd for speed. Analogously, on GPU, it uses cuSOLVER's routines gesvdj and gesvdjBatched on CUDA 10.1.243 and later, and MAGMA's routine gesdd on earlier versions of CUDA. Note The returned U will not be contiguous.Ok, I gave 100 to cusolver gesvd function. Function was working but the results of function (U, S, Vt) seems to be wrong. I mean, I can't get the matrix A from U S Vt. As my knowledge, cuSolver API assume all matrix is column-major. If I changed my matrix into column-major, m is lower than n (10x100). But gesvd function only works for m >= n.Aug 27, 2021 · Cusolver SVD for general complex matrix. Boubou63 August 27, 2021, 7:51am #1.

Introduction CUSOLVER.jl provides bindings to a subset of the CUSOLVER library. It's built on top of CUBLAS.jl, CUSPARSE.jl and CUDArt.jl. CUSOLVER.jl currently wraps all the dense solvers and the sparse solvers are in progress.Already two weeks of coding have gone past! My progress can be tracked in this issue. Part of the project is making LAPACK routines accesible from ChainerX performing computations in CPU and GPU. Another part is making them differentiable.
