Computational Thinking: I do not think it means what you think it means
“It’s a basic skill. Right along with the three Rs.” President Obama, on his weekly address just over a month ago, announced the $4-billion Computer Science for All initiative. Reactions quickly spread to make clear that the important skill is not coding, it’s computational thinking. But what does this mean? As it’s become a buzzword... Continue »

Submitted: Inexact Krylov iterations and relaxation strategies with fast-multipole boundary element method
Submitted: 19 June 2015 This paper presents a method to algorithmically accelerate boundary element methods. The fast multipole method (FMM) is already used in this context to obtain O(N) computational complexity while solving a dense linear system. Using relaxed-accuracy matrix-vector multiplications in a Krylov solver, we can achieve speed-ups in the order of 4x... Continue »
