MPI cluster environment created to execute FReMI on Amazon Ec2. The remote station represents the machine outside Amazon EC2 used to connect the MPI master instance by an SSH connection. The MPI master instance is the machine that manages the MPI slaves during the FReMI execution. It also holds the FReMI source code and the I/O files stored on the Amazon Elastic Block Store (EBS). All instances may access EBS through NFS.
