Nvidia GPUs
Two running burst of GPUgrid with Seti

Raspberry Pis
All running Einstein BRP4 work


Other news
I have 3 of the i7-6700's off  while I am running a couple of the Nvidia GPU machines. The sun is out so its warm during the day. I let the Nvidia GPUs idle during the day but nights are cool so they run overnight. The remaining i7's are crunching 24/7.


Power9 CPU
I had a look at the IBM AC922. They sport dual Power9 CPUs with up to 22 cores/88 threads. They can also be fitted with 2-6 Telsa V100 GPUs (way too expensive for me). They are an ideal number cruncher. They are installed in a number of computer clusters such as Summit at the Oak Ridge National Lab and Sierra at the Lawrence Livermore National Lab.

There are a couple of other companies also selling Power9 based computers such as Raptor Computing which have a Talos II (dual CPU machine) and a Talos II lite (single CPU machine) that is more affordable at $1399 (USD) without CPU or memory.

I'd love to get one or two of the AC922's even if they don't have Tesla's in them they'd make a great cruncher. Sadly while they run Linux out of the box and there is a BOINC client for them in Debian I would have to get various science apps and recompile them for the PPC64LE architecture and optimise them. That is something I don't have the expertise to tackle.
