DescriptionWe present DMNetwork, a high-level set of routines included in the
PETSc library for the simulation of multiphysical phenomena over
large-scale networked systems. The library
aims at
applications that have networked structures such as the ones found in electrical, gas, and water distribution systems. DMNetwork provides data and topology management, parallelization for multiphysics systems over
a network, and hierarchical and composable solvers to
exploit the problem structure. DMNetwork eases the simulation
development cycle by providing the necessary infrastructure through
simple abstractions to define and query the network components.

We will demonstrates its ability to simulate the Mississippi river network,
and to solve a system over
large networks of
water pipe distribution
with more than 2 billion variables on
extreme-scale computers using up to 30,000 processors.
