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.

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

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.

1. Setup job submission server
2. Install SSH module for PHP
3. Configure web server to submit job to local cluster
4. Testing job submission
5. Potential job submission problems
