1. Introduction The following document details the operation of the OSC accounting system, an application based on the GOLD open source HPC banking software. The main purpose of the document is to be used as a user guide for the accounting web interface and command line tools by group (project) leaders of projects registered on the OSC systems. Once an account is issued for a project leader, an automated email is send with the link and login details for the accounting system. With the aid of the accounting system group leaders can: • • •
view detailed account activity allocate users to their projects / accounts transfer credits between their accounts
2. Usage The web interface (accounting website) is available at the following address: https://radley.osc.ox.ac.uk The address above can be reached only when using the Oxford University campus machines, if you require access from remote systems please contact OSC support. The website uses a self signed SSL certificate, therefore modern browsers ( i.e. Firefox 3 , I.E 7) will ask you to accept the certificate prior to accessing the web pages. In order to login to the accounting system: 1. Use the glpasswd command from the terminal on any OSC system to create a new password.You can choose to create the same password you have for logins on OSC systems or something different. If you forgot or lost your password you can use the glpasswd command again to set a new password. 2. When you reach the accounting login page, use your regular OSC username and the password you have just created.

In order to modify your account(s) follow the Modify Account link:

Money deposited for usage on OSC systems are converted to credits where 1 credit = 1 Proccessor core*1 second of walltime. Credits from this initial account are available to all project users equally. It is possible to request for multiple accounts if you like to group part of your users and restict credit allocation per group by sending an email to the OSC support address. You will receive email confirmation when your additional account(s) have been created so you can transfer credits from your main account to it and select from this menu the users you want to have access to the credits of the new account. If you wish to restict users of additional accounts from accessing the credits of your main account do not forget to select them from this screen and set them as inactive by un-ticking the 'access' box next to their name. Like all previous menus, remember to make a selection of user names by holding down the Ctrl key and clicking on user names.
