GCC 11 vs. LLVM Clang 12 Compilers On The AMD EPYC 7763

Filed under
Graphics/Benchmarks

For those wondering how the recent releases of the GCC 11 and LLVM 12 (Clang 12) open-source compilers are competing on AMD Zen 3, here are some recently conducted benchmarks looking at that showdown on an AMD EPYC 7763 1P server.

Now that both Clang 12 and GCC 11 stable are out, fresh stable compiler benchmarks are being carried out on various AArch64 and x86_64 systems. These EPYC 7763 1P tests were wrapped up last month while waiting for that GCC 11.1 stable debut and as a result were using the GCC 11.0.1 20210413 snapshot of the time. Clang 12.0.0 was in its latest release form. Both compilers were running in their release modes.

  • 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.
