An automated multiscale ensemble simulation approach for vascular blood flow
Mohamed A. Itani, Ulf D. Schiller, Sebastian Schmieschek +6
Cerebrovascular diseases such as brain aneurysms are a primary cause of adult disability. The flow dynamics in brain arteries, both during periods of rest and increased activity, a…
Weighted decomposition in high-performance lattice-Boltzmann simulations: are some lattice sites more equal than others?
Derek Groen, David Abou Chacra, Rupert W. Nash +3
Obtaining a good load balance is a significant challenge in scaling up lattice-Boltzmann simulations of realistic sparse problems to the exascale. Here we analyze the effect of wei…
Coalesced communication: a design pattern for complex parallel scientific software
Hywel B. Carver, Derek Groen, James Hetherington +3
We present a new design pattern for high-performance parallel scientific software, named coalesced communication. This pattern allows for a structured way to improve the communicat…
