Teraproc R Cluster-as-a-Service beta is ready for test run. Users with Amazon Web Services (AWS) account can register, then launch a cluster of computers for running R batch jobs and R MPI jobs within a few minutes. It also allows users to leverage GPU to accelerate the R program performance. Other than the cost of AWS infrastructure, there is no additional cost for this service right now. To get the most out of it, user can also leverage the AWS Spot Instances. The Teraproc R Cluster-as-a-Service can be accessed here.
