DescriptionThe electric and magnetic fields around power lines
carry an immense amount of information about the power
grid, and can be used to improve stability, balance
loads, and reduce outages. To study this, extremely
large models of transmission lines over a 49.5-sq-km
tract of land near Washington, DC have been built. The
terrain is modeled accurately using 1-m-resolution LIDAR
data. The models are solved using the boundary element
method, and the solvers are parallelized across Army
Research Laboratory's Centennial supercomputer using a
modified version of the domain decomposition method. The
code on each node is accelerated using the fast
multipole method and, when available, GPUs.
Additionally, larger test models were used to
characterize the scaling properties of the code. The
largest test model had 10,020,913,152 elements, and was
solved across 1024 nodes in 3.0 hours.
