Using and Administering

System Configuration

Their processor is an SP2 using RISC System/6000 nodes linked by an internal high-speed network with a centrally managed software environment. The nodes are functionally divided into four groups of 16 each for different types of work: interactive logins, sequential job batch processing, parallel job batch processing and data, and tape and network services.

This customer uses AFS heavily. It provides the single system image for users' home directories and the files common to their experiments. Many software products are served directly out of AFS using symbolic links.

LoadLeveler provides this customer with the following facilities:

• Interactive load balancing of users across nodes on the SP2 and other UNIX services on site
• Batch services for serial compute jobs
• Scheduling for parallel applications
