As a part of the Institute of Condensed Matter Physics, the Laboratory for Quantum Magnetism perform fundamental research combining
state-of-the-art experiments with new theoretical developments. For several promising new theories and for ray-tracing simulations of a
novel scientific instrument concept, there is a need for increased computational power. Due to easy parallelisation of the computational tasks, we chose to build a custom cluster from consumer hardware. This “Quantum-Wolf” cluster will provide 5 times more GFLOPS/CHF
and consume less W/GFLOPS than a conventional fast-interconnected Xeon-based cluster.
96 nodes, 384 CPUs
9.6 TFlops (synthetic, benchmarking will follow)
312 CHF/ node
96 nodes connected through two switches. The selected hardware:
|Memory||Patriot DDR3 1333MHz 2x4GB||96|
|Power supply||FSP AURUM GOLD 600W||12|
|Fans||Arctic Cooling F12-PWM||60|
|Ethernet cables||Roline Kat. 5e Kabel 1m||96|
|Ethernet switch||Zyxel XGS1910-48||2|
A test setup with 4 nodes was assembled. Hardware, operating system and actual compute performance was verified and design optimised.
The four motherboards were powered using a single power supply connected through a custom built PCB. The total electricity consumption was 50W per node measured using a power-meter before the bower-board.
