Abstract

It is investigated to verify the scalability aspects of the distributed engineering computation on the cloud computing In the study a parallel virtual machine program distributed over a network of cloud computers is used in solving a finite difference version of a typical complicated engineering differential equation It is found that there exist a pseudo-optimal number of virtual machines which does not necessarily coincide with the number of tasks and the pseudooptimal number depends on various overheads over the network of virtual machines Increasing the number of machines in the cloud beyond certain threshold one does not improve computing performance due to the communication overhead between the task processes distributed over the network
