WebFeb 18, 2011 · Hey all, I’ve been experimenting with accelerating the computation of eigenvalues in a 25x25 matrix. To do this, I’m using Jacket, a MATLAB add-on that talks to CUDA, and a Quadro FX 5800 GPU. The short version is, Jacket takes longer to find eigenvalues for smaller matrices; I assume it’s because the processing time saved is … WebCucheb is a collection of C++ subroutines for accurately and efficiently solving large sparse matrix eigenvalue problems using NVIDIA brand GPUs. These methods are well suited …
WebTo compute y=A*x when A is symmetric and only lower triangular part is stored, two steps are needed. First step is to compute y=(L+D)*x and second step is to compute y=L^T*x + y. Given the fact that the transpose operation y=L^T*x is 10x slower than non-transpose version y=L*x, the symmetric property does not show up any performance gain. WebSep 8, 2010 · Sid. avidday September 8, 2010, 10:19am #2. Cula implements the standard Lapack routines for non-symmetric eigenvalue problems. It also includes the standard Lapack LU, QR and SVD routines that can be used for solving dense linear systems. Unfortunately it is closed source, and to get the double precision linear solvers and any …
WebLibrary requires linking to cuBLAS and cuSOLVER. Use -Mcuda=cublas,cusolver flag when linking your application to do this. This library also requires linking to a CPU LAPACK library with an implementation of the zstedc function. If NVTX is enabled with -DUSE_NVTX flag, also must link to NVTX.
