Simulating many-engine spacecraft: Exceeding 1 quadrillion degrees of freedom via information geometric regularization
Benjamin Wilfong, Anand Radhakrishnan, Henry Le Berre +9
We present an optimized implementation of the recently proposed information geometric regularization (IGR) for unprecedented scale simulation of compressible fluid flows applied to…
Targeting GPUs with OpenMP Directives on Summit: A Simple and Effective Fortran Experience
Reuben D. Budiardja, Christian Y. Cardall
We use OpenMP to target hardware accelerators (GPUs) on Summit, a newly deployed supercomputer at the Oak Ridge Leadership Computing Facility (OLCF), demonstrating simplified acces…
GenASiS Mathematics: Object-oriented manifolds, operations, and solvers for large-scale physics simulations
Christian Y. Cardall, Reuben D. Budiardja
The large-scale computer simulation of a system of physical fields governed by partial differential equations requires some means of approximating the mathematical limit of continu…
Parallel FFT-based Poisson Solver for Isolated Three-dimensional Systems
Reuben D. Budiardja, Christian Y. Cardall
We describe an implementation to solve Poisson's equation for an isolated system on a unigrid mesh using FFTs. The method solves the equation globally on mesh blocks distributed ac…
