Both Platform LSF and Platofrm MPI needs to be installed on the cluster.
Revolution R needs to be installed on every node of the cluster.
You need to setup a common share directory on each node of your cluster that will be used in running R jobs. Every LSF user needs to be able to read and write to this directory and each user should have their own subdirectory to hold information from running jobs.
You need to be able to 'ssh' from each node of the cluster to every other node in the cluster. You will need to setup either password-less ssh or key-based authentication on the cluster. Authentication can be either domain, key or host based.
Your data used in R computations must be available on all of the nodes.
