Performance tuning MPI Results of running all of the exercises in this section are available.MPI point-to-point operations typically involve message passing between two, and only two, different MPI tasks. One task is performing a send operation and the other task is performing a matching receive operation. There are different types of send and receive routines used for different purposes. For example: Synchronous send 1.2 Mesh module. A finite element mesh of a model is a tessellation of its geometry by simple geometrical elements of various shapes (in Gmsh: lines, triangles, quadrangles, tetrahedra, prisms, hexahedra and pyramids), arranged in such a way that if two of them intersect, they do so along a face, an edge or a node, and never otherwise.1.2 Mesh module.
