Building A 96-Core Ubuntu ARM Solar-Powered Cluster

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.

Making A Easy-To-Setup $50 Linux Multi-Seat Computer

While it's improved a lot recently, in the past setting up a multi-seat computer has been a pain in the ass with a lot of manual configurations needed and other peculiar steps to get the hardware/software combination working right. What if the process were a lot simpler? What if new seats could be added to a computer at a very low cost and the setup was effectively "out of the box" to the point that it's truly plug-and-play? Well, we are now effectively at that point on the Linux desktop and there is a new Kickstarter effort to help in that initiative.

Trim-Slice: Dual-Core ARM Tegra 2 Desktop

The Trim-Slice from CompuLab is a dual-core ARM Cortex-A9 nettop based on the NVIDIA Tegra 2 platform. In this article are our first Ubuntu benchmarks of this low power, fan-less desktop with comparative figures to Intel's older platforms and the OMAP4660-based dual-core ARM Cortex-A9 PandaBoard ES.

ARM Cortex-A9 PandaBoard ES Benchmarks

The performance of the dual-core ARM Cortex-A9 OMAP4460 configuration as found on the PandaBoard ES is quite commendable and in this Phoronix review the dual-core 1.2GHz ARM system with PowerVR SGX540 graphics is being compared to several Intel Atom, Pentium M, and Core Duo configurations running Ubuntu Linux throughout. To spice things up, the pre-production OLPC XO-1.75 was also thrown into the testing mix with its single-core ARMv7 800MHz Sheeva processor.

ZaReason Strata 6880 Sandy Bridge Notebook

You may have noticed several Phoronix articles in recent weeks using a ZaReason notebook built around Intel's "Sandy Bridge" processor. This is one of the new notebooks from ZaReason that had been in our labs for testing. Here is a last look at the Strata 6880 notebook from this Linux-focused PC vendor.

OLPC XO-1.75 Laptop Preview

Last month at XDC2011 Chicago, I managed to get my hands on what should be the production hardware model of the XO-1.75 laptop that is expected to be released in the coming months by the OLPC project. The low-cost OLPC laptop targeted for students is now ARM-based and consumes very little power.

Running ARM Linux Benchmarks On The HP TouchPad

While Hewlett-Packard recently announced they will be killing off their webOS devices, just days prior to that I had ordered an HP TouchPad 16GB to carry out some additional ARM-based Linux benchmarks. Although HP's devices may be going away, I am still fond of webOS and it's a fair environment to carry out performance tests.

AMD Llano Compiler Performance

Last week were a set of AMD Fusion A8-3850 Linux benchmarks on Phoronix, but for you this week is a look at the AMD Fusion "Llano" APU performance when trying out a few different compilers. In particular, the latest GCC release and then using the highly promising Clang compiler on LLVM, the Low-Level Virtual Machine.

Qualcomm Snapdragon MDP MSM8660

Beyond the new data visualizations and other plans for Lillesand, Phoronix Test Suite 3.4 will contain much greater support for Google's Android operating system and there will also be greater compatibility with ARM tests using our automated testing framework. A horde of ARM-based testing is also just out on the horizon at Phoronix.com. This is all thanks to the cooperation of Qualcomm's Innovation Center; they recently sent over the Snapdragon MDP MSM8660 for doing this work and it is an interesting and powerful phone.
