> Your new 20GB volume vol-d555839a has been created successfully > Terminating node: volhost-us-east-1c (i-c4d0dc2b) > Leaving volume vol-d555839a attached to instance i-c4d0dc2b Starcluster createvolume -shutdown-volume-host -name=physionet 20 us-east-1c As an example, we will create a 20GB volume to store (some) PhysioNet data, which can be resized to hold more if necessary. Instead, it is preferable to set up additional volumes which can be attached to each cluster as described in StarCluster's Using EBS Volumes for Persistent Storage.

Starcluster start -c wfdbcluster myclusterĪfter the cluster has started, you can ssh to the master node as root by running:įinally, you can temporarily stop the cluster by running:įor large data it is generally inefficient to download it onto to each new cluster. To deploy the most basic WFDB-specific cluster run: This can be done from the Amazon EC2 dashboard.įinally, add WFDB-specific cluster templates from this project's config to yours: Note: If this step fails, you may need to ensure that the user specified in the above has privileges to instantiate new instances. Starcluster createkey wfdbkey -o ~/.ssh/wfdbkey.rsa Third, create a WFDB keypair for accessing the instances that will be created:

Note: Depending on your account permissions, you may have to use sudo or contact your system administrator for the above command.ĭetailed steps can be found in StarCluster's quickstart guide.

However, many users can install the project using pip: The following assumes you already have an AWS account, so if you do not, head over to AWS and create one.ĭetailed and up-to-date steps can be found in StarCluster's installation documentation. Therefore, we will be using StarCluster to quickly and simply create a suitable cluster on Amazon EC2. The example processes all ECG signals from the MGH Database using Hadoop's Map interface to manage the working queue of 250 records.ĭeploying and managing a cluster is often a non-trivial task. A computationally intensive example is shown using WFDB's function for multiscale entropy, mse and surrogate data testing.

The tools used on this tutorial include StarCluster, Amazon EC2, Octave, and Hadoop. This tutorial aims to provide guidance and instructions for researchers familiar with the WFDB Software Package who are insterested in processing PhysioBank databases on a distributed cloud environment. Using the WFDB Software Package, researchers have direct access to large collection of PhysioBank databases consisting of a wide variety of physiological signals. The new PhysioNet website is available at.
