Communication Channels between CSCS and CHIPP
Twiki
Advantages:
- can optimally present information, full layout control
- multiple people can collaborate on the same page
- change record (including who) and playback of old page versions
- authn/authz
- can set mail notifications or RSS news feeds
Disadvantages
- takes a bit longer then the average email
- needs discipline to keep some order in the pages (try to keep a minimum of pages)
Usage:
- main information portal for users
- main documentation portal for admins and users
- principal place for finding all quasi-static information on the system
- VOs must specify their requirements in relation to the local Grid services on a wiki page, so that this information is accessible for the CSCS admins. This is needed, since the CSCS admins cannot be expected to follow the internal VO discussions, and often even do not have access to the restricted CERN VO twiki areas or indico
- log book of events (for admins, but also for VOs, if wanted. e.g. look at the CMSSiteLog)
Advantages:
- tracked with open/closed status, so issues are not lost
- all changes to the ticket are tracked
Disadvantage:
- Information spread over multiple entries
- only submitter and local admins see the issues
Usage:
- submission of support requests and bug reports by the VO site contacts. They should also have access to the web front end.
- Do we want users to submit to this, too? Or rather have all users use the GGUS or go via site contacts?
- requests, e.g. for the installation of a machine or a service
Mailing lists
Advantages:
- small effort
- people can filter or put triggers in their clients
- archived
Disadvantages
- information scattered throughout threads
- bad to locate information
tier2-users_at_cscs.ch |
used for broadcasting downtimes and generally technically relevant messages for users who rely on the local resources of the PHOENIX cluster (e.g. on the storage accessibility |
{$VO}-users_at_cscs.ch |
subscribed to tier2-users list, also may receive VO specific messages and can be used for discussions among users (VO site contacts read it, too) |
Chat
Advantages:
- interactive, fast
- logged, so historic information is available
Disadvantages:
- information is scattered, searching through chat logs is a pain
- bad if there are multiple simultaneous discussions going on
CSCS admins and VO-contacts try to be present on the chat.
Usage:
- emergencies
- request for fast information
- working together on a service, debugging
- discussions
