Appion

h1. Setup Remote Processing

The web interface for Appion allows one to directly login to a computer and process Appion jobs. But this requires a job submission system to be installed.

h2. Types of clusters:

* Local cluster a.k.a. processing host — this is a cluster that has all of the data directories mounted locally and all processing software installed

* Remote cluster a.k.a. cluster — this is a cluster that has a limited selection of software and the data is not accessible

h2. Local Cluster Appion processing setup

The following applies to both the web-server computer (setup earlier) and a job submission system on a local cluster. The job submission system usually consists of a head node (main computer) for receiving and scheduling jobs and individual processing nodes (slave computers) for running jobs. All of these system CAN exist on an single computer.
