Last week I shared results from the Phoronix 12-core ARM Linux mini cluster that was constructed out of six PandaBoard ES development boards. Over the weekend, a 96-core ARM cluster succeeded this build. While packing nearly 100 cores and running Ubuntu Linux, the power consumption was just a bit more than 200 Watts. This array of nearly 100 processor cores was even powered up by a solar panel.
This past weekend I was out at the Massachusetts Institute of Technology (MIT) where this build took place. A massive ARM build out has been in the plans for a few months and to even get it running off a solar panel. The build was a success and by Sunday, the goals were realized.
The bulk of the PandaBoards were not the ES model (I brought my collection of PandaBoard ES models as back-ups for the PandaBoard nodes that failed), but just the vanilla model. The non-ES model packs a Texas Instruments OMAP4430 with a dual-core 1.0GHz dual-core Cortex-A9 processor. The GPU and CPU of the PandaBoard ES with its OMAP4460 are at higher clock speeds, but aside from that it is very similar to the OMAP4430 model.
