Phoronix has constructed a low-cost, 12-core, 30-watt ARMv7 cluster running Ubuntu Linux. The developers have used six PandaBoard ES OMAP4460 dual-core ARMv7 Cortex A9 chips to make the ARM cluster. The power consumption result shows that the ARM cluster has outdone Intel Atom and AMD Fusion processors in performance per-Watt, except Intel’s latest-generation Ivy Bridge processors.
Each PandaBoard ES has 16GB SDHC Class-10 memory for storage. Its head node has NFS that can easily share a home directory to the other nodes. There are, however, some problems regrading Ubuntu 12.10 running ARM clusters. The Phoronix team said that Ubuntu 12.10 problem will be solved on this compute cluster in the coming weeks and they also hopes that the result should be in double-digit gains.
