All Linux, all the time: Supercomputers Top 500

Filed under
GNU
Linux
Server

Starting at the top, two IBM-built supercomputers, Summit and Sierra, at the Department of Energy's Oak Ridge National Laboratory (ORNL) in Tennessee and Lawrence Livermore National Laboratory in California, respectively to the bottom -- a Lenovo Xeon-powered box in China -- all of them run Linux.

Linux supports more hardware architectures than any other operating system. In supercomputers, it supports both clusters, such as Summit and Sierra, the most common architecture, and Massively Parallel Processing (MPP), which is used by the number three computer Sunway TaihuLight.

When it comes to high-performance computing (HPC), Intel dominates the TOP500 by providing processing power to 95.6% of all systems included on the list. That said, IBM's POWER powers the fastest supercomputers. One supercomputer works its high-speed magic with Arm processors: Sandia Labs' Astra, an HPE design, which uses over 130-thousand Cavium ThunderX2 cores.

And, what do all these processors run? Linux, of course.
.
133 systems of the Top 500 supercomputers are using either accelerator or co-processor setups. Of these most are using Nvidia GPUs. And, once more, it's Linux conducting the hardware in a symphony of speed.

  • Linux Powers All Of The World’s Top 500 Supercomputers

    OP500’s 53rd edition has been released and this time what lies common in all the top 500 supercomputers is Linux. The supercomputers on the list are Linux-based and capable of delivering a petaflop performance and even more.

    The top 10 on the list include Summit and Sierra supercomputers in first and second positions, respectively. Both supercomputers have been developed by the US Department of Energy (DOE) and were the top two supercomputers even in the 52nd edition of the list in November last year.

  • Linux Runs on All of the Top 500 Supercomputers, Again!

    As per the latest report from Top 500, Linux now runs on all of the fastest 500 supercomputers in the world. The previous number was 498 as remaining two supercomputers ran Unix.

    Top500 is an independent project that was launched in 1993 to benchmark supercomputers. It publishes the details about the top 500 fastest supercomputers known to them, twice a year. You can go the website and filter out the list based on various criteria such as country, OS type, vendors etc.

    Don’t worry. I am going to list some of the most interesting facts from this report. But before let’s discuss why Linux is the preferred choice of an operating system for supercomputers.

Top 500 Supercomputers of the World are Linux-Based

Late Coverage of Confidential Computing Consortium

  • Microsoft Partners With Google, Intel, And Others To Form Data Protection Consortium

    The software maker joined Google Cloud, Intel, IBM, Alibaba, Arm, Baidu, Red Hat, Swisscom, and Tencent to establish the Confidential Computing Consortium, a group committed to providing better private data protection, promoting the use of confidential computing, and advancing open source standards among members of the technology community.

  • #OSSUMMIT: Confidential Computing Consortium Takes Shape to Enable Secure Collaboration

    At the Open Source Summit in San Diego, California on August 21, the Linux Foundation announced the formation of the Confidential Computing Consortium. Confidential computing is an approach using encrypted data that enables organizations to share and collaborate, while still maintaining privacy. Among the initial backers of the effort are Alibaba, Arm, Baidu, Google Cloud, IBM, Intel, Microsoft, Red Hat, Swisscom and Tencent. “The context of confidential computing is that we can actually use the data encrypted while programs are working on it,” John Gossman, distinguished engineer at Microsoft, said during a keynote presentation announcing the new effort. Initially there are three projects that are part of the Confidential Computing Consortium, with an expectation that more will be added over time. Microsoft has contributed its Open Enclave SDK, Red Hat is contributing the Enarx project for Trusted Execution Environments and Intel is contributing its Software Guard Extensions (SGX) software development kit. Lorie Wigle, general manager, platform security product management at Intel, explained that Intel has had a capability built into some of its processors called software guard which essentially provides a hardware-based capability for protecting an area of memory.

Graphics: Mesa Radeon Vulkan Driver and SPIR-V Support For OpenGL 4.6

  • Mesa Radeon Vulkan Driver Sees ~30% Performance Boost For APUs

    Mesa's RADV Radeon Vulkan driver just saw a big performance optimization land to benefit APUs like Raven Ridge and Picasso, simply systems with no dedicated video memory. The change by Feral's Alex Smith puts the uncached GTT type at a higher index than the visible vRAM type for these configurations without dedicated vRAM, namely APUs.

  • Intel Iris Gallium3D Is Close With SPIR-V Support For OpenGL 4.6

    This week saw OpenGL 4.6 support finally merged for Intel's i965 Mesa driver and will be part of the upcoming Mesa 19.2 release. Not landed yet but coming soon is the newer Intel "Iris" Gallium3D driver also seeing OpenGL 4.6 support. Iris Gallium3D has been at OpenGL 4.5 support and is quite near as well with its OpenGL 4.6 support thanks to the shared NIR support and more with the rest of the Intel open-source graphics stack. Though it's looking less likely that OpenGL 4.6 support would be back-ported to Mesa 19.2 for Iris, but we'll see.
