Fast Safe Spline Surrogates for Large Point Clouds
To support real-time computation with large, possibly evolving point clouds and range data, we fit a trimmed uniform tensor-product spline function from one direction. The graph ...

Runtime compilation techniques for data partitioning and communication schedule reuse
In this paper, we describe two new ideas by which HPF compiler can deal with irregular computations e ectively. The rst mechanism invokes a user speci ed mapping procedure via a s...

Route Planning with Flexible Objective Functions
We present the first fast route planning algorithm that answers shortest paths queries for a customizable linear combination of two different metrics, e. g. travel time and energy...

On uniquely k-determined permutations
Motivated by a new point of view to study occurrences of consecutive patterns in permutations, we introduce the notion of uniquely k-determined permutations. We give two criteria f...

Managing the complexity of lookahead for LU factorization with pivoting
We describe parallel implementations of LU factorization with pivoting for multicore architectures. Implementations that differ in two different dimensions are discussed: (1) usin...
