The Firepear computing stack is currently all Ryzen. It’s simple cost-benefit analysis: we’re interested in crunching as much data as possible per unit time, at a reasonable cost (in both money and electricity). Right now, that’s Ryzen. We’re upgrading all our machines to the new R9 3900X CPU. This provides us an opportunity to compare all three generations of the Ryzen family. 3900X vs 3950X We want to throw as many cores as we can at the problems that we volunteer our compute time on, but we also have a finite budget.
After months of pondering what GPU to use to get my compute farm back into crunching GPGPU workunits, I was persuaded by a recent review to order a GTX 1650 and give it a go. Background and lead-up Years ago, I was reading stories about how Linux support on Steam had really improved. I decided to build a Linux box capable of running modern-ish games. This was in 2015, a time when AMD GPU support on Linux was abominable, so my choice for a video card boiled down to “which Nvidia card?
This is the development diary for Greenhouse, my attempt to build a DIY compute farm in a box. In other words, a multi-machine chassis. 2018-11-01 — Introduction and Plan The core idea is to assemble individual compute nodes on trays, in the most compact way feasible, and then to stack nodes atop each other in an enclosure. The components of each node will be: A tray made from some thin, rigid, wood-based board.
