I was wondering if this will run on ARM cpus, I tried to set it up on a Raspberry Pi and I have an error during benchmarking:
ARM is not supported, only 64bit x86 compatible (x86_64 a.k.a. AMD64)
./kardashev-sandybridge: /usr/local/cuda-8.0/targets/x86_64-linux/lib/libOpenCL.so.1: no version information available (required by ./kardashev-sandybridge)
Still it is able to compute keys at 0.79 Mkeys/s (it's a AMD Athlon X2 340 ultra cheap cpu) but I guess it's complaining because the cpu is AMD?
No, it's complaining because your OpenCL installation is slightly broken.
Reinstalling OpenCL helps. clinfo should work, if you have a Nvidia GPU, nvidia-smi should work, then you are probably good to go.
The performance you see is because you run a CPU-only generator.
In this project, you have to earn your merits and perks. One of them being to be allowed to use a GPU. Which comes after you delivered 3000 Gkeys CPU-only.
