Parallel Mesh Generation Software
While many solvers have been ported to parallel machines, grid generators have left behind. Still the preprocessing step of mesh generation remains a sequential bottleneck in the simulation cycle. That is why the need for developing of stable 3D parallel grid generator is well-justified.
A parallel version of the MeshSim mesh generator by Simmetrix Inc., is available for both research and commercial use. It includes parallel implementations of surface, volume and boundary layer mesh generation as well as parallel mesh adaptivity. The algorithms it uses are based on those in reference and are scalable (both in the parallel sense and in the sense that they give speedup compared to the serial implementation) and stable. For multicore or multiprocessor systems, there is also a multithreaded version of these algorithms that are available in the base MeshSim product
Another parallel mesh generator is D3D, was developed by Daniel Rypl at Czech Technical University in Prague. D3D is a mesh generator capable to discretize in parallel (or sequentially) 3D domains into mixed meshes.
BOXERMesh is a parallel octree mesh generator developed by Cambridge Flow Solutions. Implemented as distributed-memory fully parallelised software, it is specifically designed to overcome the traditional bottlenecks constraining engineering simulation, delivering advanced meshing on geometries of arbitrary complexity and size. Its scalability has been demonstrated on very large meshes generated on HPC clusters.

Famous quotes containing the words parallel and/or generation:
“As I look at the human story I see two stories. They run parallel and never meet. One is of people who live, as they can or must, the events that arrive; the other is of people who live, as they intend, the events they create.”
—Margaret Anderson (1886–1973)
“My generation was ... haunted by Dr. Freud’s psychoanalysis, which ... had become the latest rage among the intelligentsia. I feel sorry for the modern mothers who have not one but a whole swarm of famous psychiatrists to confuse their thinking and spoil their fun by reminding them constantly that love is a dangerous business.”
—Agnes E. Meyer (1887–1970)
