Clustering and temperature variation
Posted: Tue Apr 29, 2014 5:36 am
I promised I would get some data later tonight regarding heat distribution on my cluster setup. Here's a pretty graph.
The graph shows the temperature of each board in the stack, with the position in the legend corresponding to the vertical position in the stack. The variation in temperatures generally accompanies different positions that I tried, with each position getting about 30 seconds to normalize. I'll have a more thorough setup in later days this week.
I'm not an engineer, but it looks like for stacked boards the temperature variation depends pretty heavily on board position in the stack and relative position of the fans. This should be pretty obvious (like, really obvious), but the graph somewhat quantifies this.
I will post my scripts and additional experimental data later when I can approach it more seriously, but I need to go to bed right now.
