Dynamic, unbalanced distribution of tasks on a PS3 cluster system for double precision calculation

摘要

The article aims to describe an algorithm for dynamic distribution of tasks in a parallel computing system consisting of a network of 9 PlayStation3 (PS3) stations. Due to the fact that the SPU cores do not have units of double precision calculation, these calculations require a longer time. Therefore, an unbalanced distribution of computing tasks on a heterogeneous cluster system as 9 × PS3 is necessary. The algorithm produces an estimation of the value of n by calculating the integral π = ∫_0~1 4/1+x~2 and makes PPU-SPU empirical distribution of tasks on a smaller number of intervals. After determining the optimum loading between cores 18 × PPU (PowerPC Unit) and 54 × SPU (Synergetic Processor Unit), the integral calculation algorithm goes to a larger number of intervals.
