Cloud computing is an important branch in computer science and HPC, currently many distributed computing tasks can be performed on virtual machines that are parts of clouds public or private, and all of this without needing physical cluster. For this reason several distributed computing tasks such as scientific applications are being moved from clusters to clouds. MPI (Message Passing Interface) is a key component in common and distributed computing tasks. The virtualized environment hides the network topology information of the users, and existing optimizations based on network topology for MPI applications are no longer viable in the cloud environment, so that improvements are needed regarding these factors. Our proposal is studying the feasibility of improved latency and network traffic for parallel applications running on a cloud environment. In addition we present a study of the behavior of MPI communications in Amazon EC2 public cloud. After analyzing the current situation, we design a method called MPI Communications Management (MCM).
