Linux Clusters Target Oil & Gas Applications

Filed under
Linux

As an industry, hydrocarbon exploration and production operates in an increasingly challenging environment. The new challenges include more than high risk and high capital commitments, or declining fields and complex operations. Unconventional plays have become conventional. It is not enough to be creative, aggressive and technically adroit. One also wants to be smart. The good news is that smart is a lot cheaper than it used to be.

Specifically, high performance computers (HPCs) are a lot less expensive than they used to be, and a lot more powerful. The fastest computer in the world, Blue Gene/L, runs at nearly 300 teraflops, or 300 trillion floating point operations per second. The real revolution is that regular computer servers have become HPCs through parallel architectures, increasing industrial and market penetration.

A small cluster of Linux boxes -- 32 regular servers -- now outperforms the world's fastest computers from only a few years ago at 1/100th of the cost. They also are compact and easily serviced. A 128-cluster computer would take only three or four racks, easily fitting in a kitchen. These machines, the "big iron" of the world, have become readily available and powerful tools to tackle tough exploration, drilling and production problems.

Thunder Linux cluster at Lawrence Livermore National Laboratory (LLNL). It is an 18-teraflop machine with more than 1,000 nodes and 4,000 central processing units, and ranks as the 11th fastest computer in the world. However, Thunder is about to be surpassed by an even faster and more powerful cluster system.

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.
