This post is a follow up to a recent post in which I compared the ffmpeg video transcoding performance of a number of notebook-, workstation- and cloud server CPUs. Having done that, I’ve wondered a few days later what effect hyper-threading and dual channel RAM have on such a workload. The results are pretty interesting.
After my very good experience with running Ubuntu 20.04 on almost the latest hardware, I decided to be even more adventurous, and go for a mid-range notebook with pretty much the latest hardware, i.e. with an 11th generation Intel i5 CPU. So here’s how that went.
Last year I post-processed videos from the Vintage Computing Festival 2020 on my rather old notebook and was quite underwhelmed by the time it took. Even VMs in the cloud did not significantly speed up the process. This year I’ve had a workstation with an Nvidia graphics card and hardware H264 encoding for the purpose … Continue reading Ffmpeg Comparison – From Nvidia to Raspberry Pi 4
When traveling, I use Wi-Fi tethering with a smartphone a lot to keep my notebook and other devices connected. When staying at a place for more than just a day or two, however, I prefer a somewhat more sophisticated setup with a Linksys router running OpenWRT. No, this is not just a fancy but often … Continue reading OpenWRT and Android USB Tethering For Backhaul
Now that the non-Standalone (NSA) flavor of 5G has been pretty much established around the globe, it is likely that more focus is put on the 5G standalone (SA) flavor of the technology. In effect that means two things: Instead of using LTE as an anchor for a 5G air interface connection, 5G can stand … Continue reading Voice over NR Whitepapers
Since 2018, I’ve been working in the area of putting 5G into practice. Back then, early versions of the 3GPP Release 15 specification had become available and equipment vendors started shipping first hardware and software. The standards were not developed overnight, however, but were preceded by visions, ideas, studies, and trials by at least half … Continue reading My 6G-Kickoff
As you might have noticed on the blog, I’ve been doing a lot of hands-on exploration these days of bare metal hardware, virtual machines, containers and orchestration (e.g. Kubernetes). My motivation behind this is twofold. For one thing, I like to evolve my private cloud. Current status: 25 containers are now running in my private … Continue reading The Three Eras Of Telecom Infrastructure Hardware
When people ask me for the ‘elevator pitch’ on ORAN my quick summary is that Open-RAN aims to: 1) separate hardware from software; 2) put all software that does not require dedicated hardware on virtualized (x86) servers or into containers ‘in the cloud’ and use high speed fiber links to connect to the remaining hardware … Continue reading CPRI, eCPRI, ORAN and the Fronthaul
When we are talking about the 5G Core and implementations based on containers the story does not end with Docker containers. As a 5GC is not only based on one server and needs lots of redundancy, a management (orchestration) tool is required to manage containers across a large number of servers. There are several tools … Continue reading Kubernetes Intro – Part 1
Over the years I’ve been looking at Docker every now and then. That’s because for one thing I am interested in the concept of deploying software in lightweight containers instead of VMs and also because I am running two pieces of software in Docker containers on my servers as well. But that was it until … Continue reading Dockerize Me – My Personal Docker Bootstrap Voyage – Part 1
