IRaaS: A cloud implementation of an interface relaxation method for the solution of PDEs

Abstract

The solution of composite Partial Differential Equations is an indispensable step in numerous scientific applications. However, this is a computationally and memory demanding process for large-scale differential equations. This is especially true for multidomain/multiphysics problems, which require application of an interface relaxation (IR) methodology on the common boundaries between domains. In this paper, we present IRaaS, a cloud-based environment for the solution of multidomain/multiphysics problems. IRaaS efficiently exploits the inherent parallelism found in the solution step for the individual subdomains, thus significantly reducing computational and memory requirements. At the same time, its efficient allocation and management mechanism allocates the optimal number of resources (virtual machines), based on the total number of resources available, as well as the size of the problems for solution.
