The Register is reporting that Boise University PhD candidate Joshua Kiepert has built a 32-way Beowulf cluster from Raspberry Pis.
““In order to keep the cluster size to a minimum while maintaining ease of access, the RPis were stacked in groups of eight using PCB-to-PCB standoffs with enough room in between them for a reasonable amount of air flow and component clearance,” he writes. “This configuration suited our needs for power distribution very well since it allowed for a power line to be passed vertically along each stack.”
“Using this orientation, four RPi stacks were assembled and mounted between two pieces of acrylic. This created a solid structure in which the cluster could be housed and maintain physical stability under the combined weight of 32 Ethernet cables.”
