  • Broadcom's V3D Gallium3D Driver Nears Working Compute Shader Suppors /jh

    Broadcom's next-gen "V3D" driver (formerly known as VC5) being used by some newer Broadcom hardware but more coming down the pipeline in the future has nearly working compute shader support.

    We hope the next-gen Raspberry Pi will end up using a Broadcom SoC supporting V3D as besides much better OpenGL capabilities and performance, one of the advantages of V3D -- once the driver stack is in shape -- is compute support -- including ultimately OpenCL and Vulkan, but again more work needs to be done on the software side before that will be realized.

  • MoltenVK Now Supports Vulkan Tessellation On macOS, Other Features

    The crew working on the open-source MoltenVK layer that allows for Vulkan to run on macOS/iOS by remapping the calls to use Apple's Metal drivers just picked up a lot more capabilities.

    Headlining the new MoltenVK v1.0.34 release that was issued on Friday is support for tessellation. Vulkan tessellation support can now work on Macs! The new MoltenVK release also adds support for VK_KHR_get_surface_capabilities2 and VK_EXT_host_query_reset. On the extension front is also updated support for VK_KHR_swapchain.

All Linux, all the time: Supercomputers Top 500

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. Read more

Red Hat and SUSE Leftovers

  • Are DevOps certifications valuable? 10 pros and cons
  • Kubernetes 1.15: Enabling the Workloads
    The last mile for any enterprise IT system is the application. In order to enable those applications to function properly, an entire ecosystem of services, APIs, databases and edge servers must exist. As Carl Sagan once said, “If you wish to make an apple pie from scratch, you must first invent the universe.” To create that IT universe, however, we must have control over its elements. In the Kubernetes universe, the individual solar systems and planets are now Operators, and the fundamental laws of that universe have solidified to the point where civilizations can grow and take root. Discarding the metaphor, we can see this in the introduction of Object Count Quota Support For Custom Resources. In English, this enables administrators to count and limit the number of Kubernetes resources across the broader ecosystem in a given cluster. This means services like Knative, Istio, and even Operators like the CrunchyData PostgreSQL Operator, the MongoDB Operator or the Redis Operator can be controlled via quota using the same mechanisms that standard Kubernetes resources have enjoyed for many releases. That’s great for developers, who can now be limited by certain expectations. It would not benefit the cluster for a bad bit of code to create 30 new PostgreSQL clusters because someone forgot to add a “;” at the end of a line. Call them “guardrails” that protect against unbounded object growth in your etcd database.
  • Red Hat named HPE’s Partner of the Year at HPE Discover 2019
    For more than 19 years, Red Hat has collaborated with HPE to develop, deliver and support trusted solutions that can create value and fuel transformation for customers. Our work together has grown over these nearly two decades and our solutions now include Linux, containers and telecommunications technologies, to name just a few. As a testament to our collaboration, HPE has named Red Hat the Technology Partner of the Year 2019 for Hybrid Cloud Solutions.
  • Demystifying Containers – Part II: Container Runtimes
    This series of blog posts and corresponding talks aims to provide you with a pragmatic view on containers from a historic perspective. Together we will discover modern cloud architectures layer by layer, which means we will start at the Linux Kernel level and end up at writing our own secure cloud native applications. Simple examples paired with the historic background will guide you from the beginning with a minimal Linux environment up to crafting secure containers, which fit perfectly into todays’ and futures’ orchestration world. In the end it should be much easier to understand how features within the Linux kernel, container tools, runtimes, software defined networks and orchestration software like Kubernetes are designed and how they work under the hood.
  • Edge > Core > Cloud: Transform the Way You Want
    For more than 25 years, SUSE has been very successful in delivering enterprise-grade Linux to our customers. And as IT infrastructure has shifted and evolved, so have we. For instance, we enabled and supported the move to software-defined data centers as virtualization and containerization technologies became more prevalent and data growth demanded a new approach.
  • SUSE OpenStack Cloud Technology Preview Takes Flight
    We are pleased to announce that as of today we are making a technology preview of a containerized version of SUSE OpenStack Cloud available that will demonstrate a future direction for our product. The lifecycle management for this technology preview is based on an upstream OpenStack project called Airship, which SUSE has been using and contributing to for some time. This follows our open / open policy of upstream first and community involvement.

NSA Back Doors in Windows Causing Chaos While Media is Obsessing Over DoS Linux Bug

  • U.S. Government Announces Critical Warning For Microsoft Windows Users
    The United States Department of Homeland Security's Cybersecurity and Infrastructure Security Agency (CISA) has gone public with a warning to Microsoft Windows users regarding a critical security vulnerability. By issuing the "update now" warning, CISA has joined the likes of Microsoft itself and the National Security Agency (NSA) in warning Windows users of the danger from the BlueKeep vulnerability. This latest warning, and many would argue the one with most gravitas, comes hot on the heels of Yaniv Balmas, the global head of cyber research at security vendor Check Point, telling me in an interview for SC Magazine UK that "it's now a race against the clock by cyber criminals which makes this vulnerability a ticking cyber bomb." Balmas also predicted that it will only be "a matter of weeks" before attackers started exploiting BlueKeep. The CISA alert appears to confirm this, stating that it has, "coordinated with external stakeholders and determined that Windows 2000 is vulnerable to BlueKeep." That it can confirm a remote code execution on Windows 2000 might not sound too frightening, this is an old operating system after all, it would be unwise to classify this as an exercise in fear, uncertainty and doubt. Until now, the exploits that have been developed, at least those seen in operation, did nothing more than crash the computer. Achieving remote code execution brings the specter of the BlueKeep worm into view as it brings control of infected machines to the attacker.
