  • Building A 96-Core Ubuntu ARM Solar-Powered Cluster

    Linux on ARMLast 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.

  • 12-Core ARM Cluster Benchmarked Against Intel Atom, Ivy Bridge, AMD Fusion

    Linux on ARMLast week I shared my plans to build a low-cost, 12-core, 30-watt ARMv7 cluster running Ubuntu Linux. The ARM cluster that is built around the PandaBoard ES development boards is now online and producing results... Quite surprising results actually for a low-power Cortex-A9 compute cluster. Results include performance-per-Watt comparisons to Intel Atom and Ivy Bridge processors along with AMD's Fusion APU.

  • Clang Compiling Against GCC On Ubuntu ARM Linux

    Linux on ARMHere's an update on the LLVM/Clang vs. GCC compiler benchmarking on ARM hardware under Linux. Last month on Phoronix I shared a few basic benchmarks of GCC vs. LLVM/Clang Compilers On ARMv7 Linux. GCC 4.6.3 on Ubuntu 12.04 was doing much better than LLVM/Clang 3.0 from the Precise repository.

  • Ubuntu 12.10 Sets To Make ARM Even Stronger

    Linux on ARMWhile Ubuntu 12.04 already did a very good job at enhancing the ARM performance, Ubuntu 12.10 already has a number of performance improvements for ARM devices. With Ubuntu 12.04 for ARM there were performance improvements thanks to switching to ARM hardfp binaries by default rather than the soft floating-point version.

  • GCC vs. LLVM/Clang Compilers On ARMv7 Linux

    Linux on ARMWhile comparing compiler performance of different Linux code compilers on different software stacks and hardware configurations is nothing new at all to Phoronix, usually it's done on x86 hardware. However, with ARM hardware becoming increasingly common and much more powerful, here's a comparison of the GCC and LLVM/Clang compilers on a dual-core ARM development board.

  • Ubuntu 12.04 LTS ARMv7 Linux Performance Gains

    Linux on ARMEarlier in the Ubuntu 12.04 LTS "Precise Pangolin" development cycle I noted some performance improvements happening on the ARM side, particularly for Texas Instruments OMAP4. Namely, Ubuntu 12.04 was ARMing up for better performance with ARM hard-float support and the performance becoming more compelling for the PandaBoard ES hardware with proper cpufreq support. In this article is a comparison of the Ubuntu 11.10 and Ubuntu 12.04 ARM performance.

  • Raspberry Pi review

    Linux on ARMIt's been the most highly anticipated launch in the history of development boards, but one of the most problem-ridden too. Originally unveiled early last year with a suggested launch schedule of September 2011, the Raspberry Pi single-board computer has proven a beast to get out of the door - but the first retail models are finally landing in customers' hands this week.

  • Take Two: Comparing JVMs on ARM/Linux

    Linux on ARMAlthough the intent of the previous article, entitled Comparing JVMs on ARM/Linux, was to introduce and highlight the availability of the HotSpot server compiler (referred to as c2) for Java SE-Embedded ARM v7,  it seems, based on feedback, that everyone was more interested in the OpenJDK comparisons to Java SE-E.  But there were two main concerns:

  • NVIDIA Tegra 3 Makes For Fast Ubuntu On ARM

    Linux on ARMHere are the first set of benchmarks of the quad-core NVIDIA Tegra 3. Needless to say, four Cortex-A9s combined with NVIDIA graphics leads to a fairly fast ARMv7 experience when running Ubuntu Linux.

  • Linux on ARM: xz kernel decompression benchmarks

    Linux on ARMI recently managed to find time to clean up and submit my patches for xz kernel compression support on ARM, which I started working on back in November, during my flight to Linaro Connect. However, it was too late as Russell King, the ARM Linux maintainer, already accepted a similar patch, about 3 weeks before my submission. The lesson I learned was that checking a git tree is not always sufficient. I should have checked the mailing list archives too.

  • ARM On Ubuntu 12.04 LTS Battling Intel x86?

    Linux on ARMIn recent weeks I have shown how Ubuntu 12.04 is ARM-ing up for better performance on the ARMv7 architecture by enabling hard-float builds and how the TI OMAP4 support has come together resulting in significant performance gains. Nevertheless, how is modern ARM hardware now comparing to the low-end Intel x86 competition? In this article are some results from Ubuntu 12.04 comparing the ARM performance to some Intel Core, Pentium, and Atom hardware.

  • Comparing JVMs on ARM/Linux

    Linux on ARMFor quite some time, Java Standard Edition releases have included both client and server bytecode compilers (referred to as c1 and c2 respectively), whereas Java SE-Embedded binaries only contained the client c1 compiler. The rationale for excluding c2 stems from the fact that (1) eliminating optional components saves space, where in the embedded world, space is at a premium, and (2) embedded platforms were not given serious consideration for handling server-like workloads.

  • Ubuntu 12.04 ARM Performance Becomes Very Compelling

    Linux on ARMLast week I delivered benchmarks showing how Ubuntu 12.04 is ARM-ing up for better performance with ARM-based hardware and detailed some of the plans Canonical has for this architecture going forward. 

  • Ubuntu 12.04 Is ARM-ing Up For Better Performance

    Linux on ARMAs shared on Phoronix in many articles already, Canonical has big plans for Ubuntu in the ARM-space. They are looking forward to making Ubuntu Linux be the first operating system to support the forthcoming ARM Cortex A15, but before that and the other achievements they have planned, they must first ship Ubuntu 12.04 LTS.

  • Ubuntu 11.04, 11.10, 12.04 On The NVIDIA Tegra 2

    Linux on ARMFor those that were interested by the CompuLab Trim-Slice, a desktop built around the ARM-based NVIDIA Tegra 2 platform, here are some more benchmarks. This time the numbers are looking at the performance of the dual-core ARM Cortex A9 system when using the Ubuntu 11.04, 11.10, and 12.04 packages.

  • Arch-ing ARM: Running Arch Linux On The NVIDIA Tegra 2

    Linux on ARMThe CompuLab Trim-Slice is quite an interesting dual-core ARM Tegra 2 device. This nettop/desktop-oriented system ships with Ubuntu 11.04 by default, but it is also well supported by Arch Linux. In this article are some tests of the dual-core ARM Cortex-A9 1.0GHz system running under Arch.

  • CompuLab Trim-Slice: Dual-Core ARM Tegra 2 Desktop

    Linux on ARMThe 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.

  • TI OMAP4660 ARM Cortex-A9 PandaBoard ES Benchmarks

    Linux on ARMThe 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.

  • AppliedMicro Showcases World's First 64-bit ARM v8 Core

  • OLPC XO-1.75 Laptop Preview

    Linux on ARMLast 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.
