CUDACLAW: A high-performance programmable GPU framework for the solution of hyperbolic PDEs
H. Gorune Ohannessian, George Turkiyyah, Aron Ahmadia +1
We present cudaclaw, a CUDA-based high performance data-parallel framework for the solution of multidimensional hyperbolic partial differential equation (PDE) systems, equations de…
Optimizing the Performance of Streaming Numerical Kernels on the IBM Blue Gene/P PowerPC 450 Processor
Tareq M. Malas, Aron J. Ahmadia, Jed Brown +2
Several emerging petascale architectures use energy-efficient processors with vectorized computational units and in-order thread processing. On these architectures the sustained pe…
Optimal stability polynomials for numerical integration of initial value problems
David I. Ketcheson, Aron J. Ahmadia
We consider the problem of finding optimally stable polynomial approximations to the exponential for application to one-step integration of initial value ordinary and partial diffe…
PyClaw: Accessible, Extensible, Scalable Tools for Wave Propagation Problems
David I. Ketcheson, Kyle T. Mandli, Aron Ahmadia +5
Development of scientific software involves tradeoffs between ease of use, generality, and performance. We describe the design of a general hyperbolic PDE solver that can be operat…
