Abstract

Usually, scheduling algorithms are designed for task-graphs. Task-graphs model oblivious algorithms, but not iterative algorithms where the number of iterations is unknown (e.g. while-loops). We generalize scheduling techniques known for oblivious algorithms to iterative algorithms. We prove bounds for the execution time of such algorithms in terms of the optimum.
