Site Systems

Purpose - APAC Partners and associated research institutes intend providing a variety of systems resources to the grid including: gatekeeper systems, test and production compute resources, data resources and web servers. This component identifies these systems and their operating configuration.

Responsible Group - Implementation Task Force

Contact - David Bannon

Technology - Centos, Xen and various other versions of linux

Inputs - This layer has no dependencies on other components

Outputs

• Gatekeepers supporting multiple grid stacks
• Standardised execution environments
• Dtandardised file system environment
• Data collection on resource use, output to Accounting
• User execution envronments, required by grid staging and execution

Grid Plans

The following site specific plans identify:

• The compute and data resources that will be made available through the grid
• How the gatekeeper machines will be wired into the site
• Details of file sharing arrangements
• Details on firewalls (and their owners) between the systems and grangenet and aarnet
• User account management (per system or site) and the implementation technology

VPAC

QUT (as one of the QPSF Partners)

• Users have the same name, but not the same UID.
• There is no large scale data storage.
• All firewalls are under QUT control.

IVEC

SAPAC

APAC National Facility

• ngdata VM will instead be implemented as services on MDSS server
• User accounts stored in LDAP database
• separate file systems on each compute cluster
• MDSS massdata filesystem long-term tape-backed storage
