1. Definitions

   UI	NorduGrid User Interface
   GM	NorduGrid Grid Manager
   Bookkeeping database	Any database server capable of keeping the data and supporting GSI authorization
   User SN	Subject Name of a user's certificate
   VO	Virtual Organisation

2. Functionality

There should be a database, with GSI-based authentication and authorisation, and it should be as redundant as MDS, i.e., based on more than one server. Known candidates are OpenLDAP and MySQL.

Information into such a database should be written by the UI and the GM, in a following manner:

1. UI, after each job submission, writes:

• Job ID

• Job name

• User SN

• User VO affiliation

• Submission time

• Submission machine (client)

• NorduGrid client (UI) version

• Client Globus middleware version

• List of input files

• Executable with parameters

• List of output files

• Requested runtimeenvironment

• Requested memory

• Requested CPU

• Requested disk space

• List of uploaded files with size

• Execution cluster (gatekeeper)

2. GM, while job proceeds, writes:

• Execution node name

• Execution node CPU type

• Execution node memory

• Execution node OS

• NorduGrid server version

• Server Globus middleware version

• List of downloaded files with size

• Status changes with timestamp

• At the end: consumed CPU time

• At the end: consumed wall time

• At the end: consumed memory

• At the end: PBS message(s)

• At the end: list of uploaded files with size

3. UI, upon job retrieval or clean-up, writes:

• Action type with timestamp

• list of retrieved/erased files

4. GM, upon deletion of non-retrieved job, writes:

• Action type (clean-up) with timestamp

• List of erased files
