Software components that make up the “PUMI components.”

The Parallel Unstructured Mesh Infrastructure provides a mesh database with O(1) adjaceny information and mesh adaption on CPUs.

PUMI-PIC provides efficient datastructures and algorithms for particle-in-cell computations.

Omega_h provides a mesh database with O(1) adjacency information and mesh adaptation on GPUs.

PCMS provides parallel control and field transfer operations for tightly coupled simulations.
