Virtualization for Embedded Systems Series: Containers Deep Dive

In the previous post, I looked at several real-world use cases for containers and hypervisors. This post will be a deep dive into containers and a how-to on using them. Note: all the code, Dockerfiles, etc. are archived in a git repo at GitHub. Container History Origins A little history is needed before we jump into building and deploying containers. Docker, which is likely still the largest container technology provider by a longshot, was originally released in 2013. In just…

Multicore Processor Modes of Operation

Multicore processors were first introduced in the early 2000’s, and were pervasive in common computing platforms by the 2010’s. The industry started with dual core chips, and then quad core, and now we are up to 48 cores! When the hardware industry brought multicore chips to fruition, the software community had to invent new ways to utilize those additional cores. I’d like to use this post to discuss a few of the common multicore software utilization schemes or modes and…

Better Systems Management Through COTS Technology

The concept of computing has been around almost as long as the mathematics from which it derives its usefulness. The world of computing as we know it today only began in the last century or so, and really only since the invention of the bipolar transistor. Fast-forward to the modern era of computing wherein we have unfathomable computing power surrounding us daily. Computing platforms and the related technology is driving advancement in every industry across the globe. From research to…
