Power measurements and cooling of the DOME 28nm 1.8GHz 24-thread ppc64 μserver compute node

Within the IBM/ASTRON DOME μServer project, we are finishing two types of memory DIMM-like sized compute nodes. The first is based on the 4-core/4-thread 2.2 GHz P5040 45nm SoC and the second on a 12-core/24-thread 1.8 GHz T4240 28nm SoC. Both SoCs employ the 64-bit Power instruction set. We show T4240 Specbench performance results, power consumption, describe the packaging of our first P5040 based 8-way hot-water cooled cluster and privide an outlook.
