Description

Pingo is appropriate for solving large compute and memory intensive parallel jobs. The Cray XT5 runs a lightweight Linux operating system (OS) on the compute nodes. Many features that are non-essential to a HPC workload have been removed from this OS. The net result is greater amounts of memory available to user applications and reduced run-time variability.

Pingo runs the Cray Linux Environment and the PBS batch system scheduler. It is attached to ARSC's mass storage system including robotic tape library.
