Optimising Recursive Functions Yielding Multiple Results in Tuples in a Lazy Functional Language
Abstract. We discuss a new optimisation for recursive functions yielding multiple results in tuples for lazy functional languages, like Clean and Haskell. This optimisation improve...

Facilitating worst-case execution times analysis for optimized code
In this paper we present co-transformation, a novel approach to the mapping of execution information from the source code of a program to the object code for the purpose of worst-...

Timing Anomalies in Dynamically Scheduled Microprocessors
Previous timing analysis methods have assumed that the worst-case instruction execution time necessarily corresponds to the worst-case behavior. We show that this assumption is wr...

Pipeline Timing Analysis Using a Trace-Driven Simulator
In this paper we present a technique for Worst-Case Execution Time WCET analysis for pipelined processors. Our technique uses a standard simulator instead of special-purpose pipel...

Evaluation of a Semi-Static Approach to Mapping Dynamic Iterative Tasks onto Heterogeneous Computing Systems
To minimize the execution time of an iterative application in a heterogeneous parallel computing environment, an appropriate mapping scheme is needed for matching and scheduling th...

Evaluating iterative improvement heuristics for bigraph crossing minimization
The bigraph crossing problem, embedding the two node sets of a bipartite graph G = V0;V1;E along two parallel lines so that edge crossings are minimized, has application to placeme...

A Parallel Algorithm for Singular Value Decomposition as Applied to Failure Tolerant Manipulators
The system of equations that govern kinematically redundant manipulators is commonly solved by nding the singular value decomposition (SVD) of the corresponding Jacobian matrix. T...
