Modeling Task Mapping for Data-intensive Applications in Heterogeneous Systems
Martin Wilhelm, Hanna Geppert, Anna Drewes +1
We introduce a new model for the task mapping problem to aid in the systematic design of algorithms for heterogeneous systems including, but not limited to, CPUs, GPUs and FPGAs. A…
Internal versus external balancing in the evaluation of graph-based number types
Hanna Geppert, Martin Wilhelm
Number types for exact computation are usually based on directed acyclic graphs. A poor graph structure can impair the efficency of their evaluation. In such cases the performance…
On error representation in exact-decisions number types
Martin Wilhelm
Accuracy-driven computation is a strategy widely used in exact-decisions number types for robust geometric algorithms. This work provides an overview on the usage of error bounds i…
Restructuring expression dags for efficient parallelization
Martin Wilhelm
In the field of robust geometric computation it is often necessary to make exact decisions based on inexact floating-point arithmetic. One common approach is to store the computati…
Multithreading for the expression-dag-based number type Real_algebraic
Martin Wilhelm
Many algorithms, especially in the field of computational geometry, are based on the premise that arithmetic operations are performed exactly. Real machines are based on inexact fl…
Balancing expression dags for more efficient lazy adaptive evaluation
Martin Wilhelm
Arithmetic expression dags are widely applied in robust geometric computing. In this paper we restructure expression dags by balancing consecutive additions or multiplications. We…
