Parallel Netgen / NGSolve
Netgen/NGSolve supports distributed memory MPI - parallelization.
To compile parallel Netgen/NGSolve you need the following packages installed:
- mpi (tested with openmpi, mpich2)
- metis (mesh partitioning library)
Configure Netgen and NGSolve with:
./configure --enable-parallel CXX=mpic++
run Netgen in parallel (with 8 processes) with
mpiexec -np 8 netgen
NGS parallelization supports:
- mesh distribution:
testing: load mesh will distributed it
- parallel NGSolve - pde data structure including fespaces, biforms, distributed sparse matrices
- BDDC preconditioning
- parallel direct solver mumps
MPI and OpenMP
- parallel compute thread is supported, but it requires multi-threading capable MPI
openmpi (tested with 1.4.3) needs configuration with --enable-mpi-threads
- openmp threads are disabled
