CAMP: Cluster Account
Management Program
• Primarily an accounting system for user
information.
• Information repository (postGresQL).
• Uses Network Information System (NIS)
to implement/enforce the information in
the database.
• Its a command line utility.

Camp and NIS/netgroups
• Python was used as a glue language to
connect the database and NIS.
• Camp uses netgroups to manage users
across hosts. (normally cluster
headnodes)
• Netgroups allows a logical grouping of
users into projects.
• Netgroups also allow CAMP to modify
user permissions on the central NIS
server,
ypbind.

C2G: What is it?
• A glue for connecting commandline
programs.
• A fairly simple display system, with an
API that allows for other programs to
use it.
• An API for other programs to
communicate with cluster systems in a
secure fashion.

C2G Goals:
• Make it a modular system, so that many
different programs can use it for a
display system.
• Make it run remotely, so that users do
not have to be on the actual cluster.
• Provide a mechanism so that utility
writers that use C2G can independently
display their results.
