F@H doesn't seem to have many CPU WUs available, but it's keeping my GPU fed. R@H has plenty of CPU WUs though (some of which are labeled COVID-19), so I'm running both and just set F@H to only use the GPU and R@H to only use the CPU.

My desktop is burning about 325W continuously (stock CPU clocks, 80% performance target for GPU) which will cost about $35/month if I run it nonstop at $0.15/kWh. The combined workload is actually hitting the efficiency sweet spot on the power supply; the UPS reports a power factor of 0.95.

I've spent many hours today messing with fan curves and voltages and clock speeds, and this is definitely scratching the itch to tinker. I also get to watch numbers go up and maybe it'll help with the COVID-19 so that's a bonus.

How much are you willing to spend on hardware, how much more of an electric bill are you willing to pay, and what aspect of this is most interesting to you? Are you more interested in optimizing for points/watt or hardware cost/point? Which projects do you want to run? If you just want to tinker with setting up a cluster of SBCs then get whichever one's most interesting to you and figure out how to make BOINC work on it. In the end you're making a donation so I recommend going for whatever setup is going to yield the most enjoyment and fit in your budget.

I'm running jobs because I want to contribute to science and don't want to spend a penny on hardware primarily for this, so I just run it on the machines I already own for other purposes.

Sometimes F@H just doesn't have a work unit to hand out. They've had a big increase in users processing WUs since COVID-19 hit.

Is anyone else getting hardware fever? Or at least hardware info fever? I want to plan a round of upgrades for later (likely much later) this year, but neither AMD or Nvidia are releasing any info on what's coming next for their product stacks.

The other day I found myself thinking about upgrading my low-end nodes to 3950Xs, which is just crazy talk with the 4000s on the (indefinite) horizon.

I had beaten my hardware addiction before grid computing pulled me back in. Now it's all "in the service of mankind", so I can justify almost anything. Thanks, science.

Yep, same. I keep reminding myself that grid computing is intended to be using the idle cycles on hardware I already own. Upgrading for the sake of make number go up faster is just an expensive form of masturbation.

It's cool enough outside now so I'm turning on the space heater again. I got my fan curves and power limits dialed in so both CPU and GPU stay at a quiet and comfortable 65C while burning ~315W.

Folding@Home on the GPU, Rosetta and TN-Grid on the CPU.
