Abstract
In this paper, we present an efficient and simple solution to the parallelization of discrete integration programs of ordinary differential equations (ODE). The main technique used is known as loop tiling. To avoid the overhead due to code complexity and border eects, we introduce redundant tasks and we use non parallelepiped tiles. Thanks both to cache reuse (4.3) and coarse granularity (24.5) , the speedup using 25 processors over the non-tiled sequential implementation is larger than 106. We also present
