Olympus: A green supercomputer for the U. S.

Pacific Northwest National Laborator

The DoE’s Pacific Northwest National Laboratory recently unveiled Olympus, a new 162-teraflop supercomputer. It’s the lab’s first large-scale supercomputer and has the computational speed and power of about 20,000 PCs. The $4.4 million computer features a closed-loop, water-based cooling subsystem, unlike other large-scale computers, which rely on air cooling. The new cooling subsystem should save the lab $61,000 annually in electricity.

The new computer also has:
– 80 Gbytes/sec of disk bandwidth, meaning it can read and write data to a disk about 800 times faster than a typical PC.
– 38.7 terabytes of memory.
– 604 Atipa computer nodes, including 1,200 dual AMD Interlagos 16-core processors.
– About 3.75 miles of cabling, including a 684-port QLogic core switch.
