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.
The following applies to the both a web-server computer (setup earlier) and job submission system. The job submission system usually consists of a head node (main computer) and individual processing nodes (slave computers) for running jobs. As of these system can exist on an individual computer.
# [[Setup job submission server]]
# [[Install SSH module for PHP]]
# [[Configure web server to submit jobs]]
# [[Testing job submission]]
# [[Potential job submission problems]]
h2. Remote Appion Processing through ssh
A more advanced way to run appion script is done through an ssh session. This is equivalent of having you ssh into a computer and starting the appion processes.
There are two kinds of appion processes:
* The first is a single-node process that can be run on a stand-alone workstation or the head-node of a computer cluster without PBS.
* The second is a multiple-node process that requires PBS to run on the cluster.
When you use "Just Show Command" option, it is always a single-node process, but if you run through ssh it could be either, depending on the demand of the process. For example, imageuploader.py is typically always run as single-node process while maxlikeAlignment.py is either run on single-node with "Just Show Command" or as a PBS job submission when you run through ssh.
