This page outlines the procedures and responsibilities for the person currently acting as 'IPP Processing Czar'. In a nutshell, these include:

• monitoring the various pantasks servers running on the production cluster
• alerting the IPP group to any notable errors or failures
• keeping an eye on production cluster load using 'ganglia'
• adding and removing labels based on the current set of processing priorities, outlined here

Setup

You will need to have ipp user access on the production cluster. For convenience, have someone with access (anyone on the IPP team) add your ssh public key to ~ipp/.ssh/authorized_keys.

Resources

Mostly, you be logged into a production cluster machine using and using the pantasks_client program to monitor operations, however there are other useful resources.

• ​Ganglia - For monitoring load on production cluster machines

Rebuilding the IPP code

The IPP in use presently is in

~ipp/ipp-20100211

If the code needs an update and rebuild, then:

• stop pantasks (as above)
• cd ~ipp/ipp-20100211
• svn update
• psbuild -optimize
• restart pantasks (as above)
