The Triton Resource Petascale Data Analysis Facility (PDAF) is a data-intensive processing resource, with some of the largest memory capacity of any publicly available system. The PDAF is designed for extremely large datasets, to provide unrivaled processing power for users with massive data management and manipulation requirements.

The resource features 28 Sun x4600M2, eight-processor quad-core nodes. Eight have 512 gigabytes of memory, and the remaining 20 have 256 gigabytes. Four of the 256-gigabyte nodes are configured for experimentation as local database servers, two with 24 terabytes and two with 7.6 terabytes.

The nodes have four 10-gigabit Myrinet connections to multiple research networks and separate interconnects for support and administration. The total system bandwidth is 112 gigabytes per second.

The 256-gigabyte nodes have eight gigabytes per core and the 512-gigabyte nodes have 16 gigabytes per core. Currently each node has eight AMD 8380 Shanghai 4-core processors running at 2.5 gigahertz.

The system has a total peak throughput of nine teraflops and a total memory capacity of nine terabytes.
