In this paper, we describe a new kind of domain decomposition strategy for solving linear elliptic boundary-value problems. It outperforms the traditional ones in complex and heterogeneous networks like those for grid computing. Such a strategy consists of a hybrid numerical scheme based on a probabilistic method along with a domain decomposition, and full decoupling can be accomplished. While the deterministic approach is strongly affected by intercommunication among the hosts, the probabilistic method is scalable as the number of subdomains, i.e., the number of processors involved, increases. This fact is clearly illustrated by an example, even operating in a grid environment.
