In my case, the majority of the runtime is taken by phase `11`, symbolic factorization, with METIS. Additionally, only a single node is used in an otherwise `MPI`-enabled application.</P> <P>I was wondering if there is a way to use `parMETIS` for fill-reducing ordering, in order to benefit from the cluster environment. One thing that would help tremendously is the source code for `cluster_sparse_solver`.</P> <P><SPAN style="font-size: 12px; line-height: 18px;">The version of MKL in question is mkl 11.2u3, which was bundled with composer_xe 2015 3.187.</SPAN></P> <P>Thanks!</P> Tue, 25 Aug 2015 22:08:35 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Using-MPI-parMETIS-with-cluster-sparse-solver/m-p/996451#M18310 Ivan_K_6 2015-08-25T22:08:35Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Using-MPI-parMETIS-with-cluster-sparse-solver/m-p/996452#M18311 <P>Ivan, that's not possible into this version.
