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...

An Undecidable Linear Order That Is n-Decidable for All n
A linear order is n-decidable if its universe is N and the relations determined by n formulas are uniformly computable. This means that there is a computable procedure which, when ...
