  • TensorFlow™ gets native support for PowerVR® GPUs via optimised open-source SYCL™ libraries
  • Imagination Getting Behind Open-Source SYCL Libraries For TensorFlow

    The SYCL train continues rolling: besides this single-source high-level C++ target for OpenCL playing a big role at Intel with their forthcoming oneAPI and as part of that also working on SYCL LLVM support for upstream, new SYCL learning courses, and other industry adoption around this Khronos standard, Imagination Technologies is getting behind it in at least one way.

  • Introducing Remote Content Caching with FSSpec

    Fsspec is a library which acts as a common pythonic interface to many file system-like storage backends, such as remote (e.g., SSH, HDFS) and cloud (e.g., GCS, S3) services.

    In this article, we will present its new ability to cache remote content, keeping a local copy for faster lookup after the initial read. Similar text first appeared in the fsspec documentation, but here we provide more details and use cases.

    This work was inspired by the caching mechanism in Intake, which proved useful and popular, but was a) rather difficult to use for all but the simplest cases and Cool only available within Intake catalogs, so not of use to any other people. Now we have made a similar concept available at a lower level.

  • Calibrating your fear of big bad optimizing compilers

    This article was contributed by Jade Alglave, Will Deacon, Boqun Feng, David Howells, Daniel Lustig, Luc Maranget, Paul E. McKenney, Andrea Parri, Nicholas Piggin, Alan Stern, Akira Yokosawa, and Peter Zijlstra

    As noted earlier, when compiling Linux-kernel code that does a plain C-language load or store, as in "a=b", the C standard grants the compiler the right to assume that the affected variables are neither accessed nor modified by any other thread at the time of that load or store. The compiler is therefore permitted to carry out a surprisingly large number of optimizations, any number of which might ruin your concurrent code's day. Given that current compilers usually do not emit diagnostics warning of potential ruined days, it would be good to have other tools take on this task. One such tool is the Kernel Thread Sanitizer (KTSAN), but its great strength, the ability to analyze huge bodies of code such as the Linux kernel, is also its great weakness, namely the need to use approximate (though still quite good) analysis techniques.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
