While going through the documentation, I came across options for DMP linear solvers but couldn't find any with SMP. Could somenone please guide me to any such possibilities within the library or through interface to some external library. You could also go through PETSc. You can build the

Paras, You could try to use SuperLU_MT (see https://portal.nersc.gov/project/sparse/superlu/) but we don't have wrapper for it. The Krylov solver in deal.II are multithreaded but the preconditioners are not. What you can try is to use deal.II solvers and STRUMPACK

[deal.II] solving stabilized Stokes

2020-02-14 Thread Richard Schussnig
Hi everyone! I am currently implementing some stationary Stokes solvers based on step-55. Therein, Taylor-Hood elements are being used. One can check the optimal order of convergence easily comparing to the Kovasznay or Poisuille flow solution, the first one being already implemented in this

[deal.II] Shared Memory Parallel Linear Solver

Dear deal.ii Community, I am working on finite deformation hyperelasticity problem which is essentially a nonlinear-vector-valued problem with displacement as the unknown at each support point(dim=2,3). *With regards to parallelism, we currently restrict ourselves to shared memory parallel

Here is a summary of the installation process on Cray XC50. I have configured deal.II with MPI, LAPACK, SCALAPACK, PETSc and p4est. Our system didn't have p4est so I started with installing it. All cray libraries are in /opt/cray/pe/lib64/ in out system. *Installing p4est* 1. Download source
