Abstract

Recently self-simulation algorithms have been developed to execute algorithms on a reconfigurable mesh (RM) of size smaller than recommended in those algorithms. Optimal slowdown, in self-simulation, has been achieved with the compromise that the resultant algorithms fail to remain AT2 optimal. In this paper we introduce, for the first time, the idea of an adaptive algorithm which runs on RM of variable sizes without compromising the AT2 optimality. We support our idea by developing adaptive algorithms for sorting items and computing the contour of maximal elements of a set of planar points on RM.
