So I need to split matrix into two parts and put them into two different compute nodes respectively. The first part is from row 1 to row n, the second part is from row n to the last row. Since the selection of row n is arbitrary, which selection will give the best performance, tow compute nodes have similar number of rows or similar number of nonzero elements?</P> Tue, 30 Sep 2014 01:52:55 GMT Chaowen_G_ 2014-09-30T01:52:55Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/how-to-split-matrix-in-cluster-sparse-solver-similar-number-of/m-p/1008423#M19111 <P>Hi:</P> <P>&nbsp;&nbsp; I need to use cluster_sparse_solver to solve a larger complex symmetric matrix.
