Hence, it can be worth the effort to use a sparse matrix solver instead of a dense LU-decomposition. This paper reports on experiences with the direct sparse matrix solvers MA28 by Duff, Y12M by Zlatev et al. and one special-purpose matrix solver, all embedded in the parallel ODE solver...
In these settings a conjugate gradient solver (or one of its variants [Barrett et al. 1994]) is often appropriate. Im- plementing such solvers on the GPU requires the construction of (1) data structures for sparse matrices, (2) data parallel algorithms for sparse matrix vector multiplies, ...

Hi, I encountered an error reminding not enough merory. The machine I used das 128Gb of RAM. And I have checked that during the initial solving, the RAM is under 15% usage. There should be enough RAM. And my model is not that complex with only 19647 elem
我从R中得到一个矩阵,用Rcpp连接R和cpp,把这个矩阵作为函数cpp_sparse_solver的一个参数,用sparseView()把它转化为SparseMatrix,声明求解器,用一个恒等矩阵来计算和求解系统然而,我得到错误“特征::MatrixXd不是一个模板”。我不是cpp的专家,所以我想要一些关于可能的错误的提示。/Den 浏览8提问于2022-11-18...

Nearly defective matrices are among challenging matrices for the performance of solver. Such matrices should be handled separately in order to get rid of potential performance bottleneck. Clustered eigenvalues observed via Gerschgorin circles may be used to detect nearly defective matrix. We observe that...
