Benchmark exists immediately (no errors) mining results in 0 I/s, 0 Sols/s

[huysamen]

Running on Intel dual Xeon SR1500ALR server (no GPU)

I followed the installation instructions as per the README, with the following 3 changes:

1. Did not install CUDA (as there is no GPU)
2. Installed fasm with apt-get and pointed fasm in the cpu_xenoncat/asm_linux folder
3. Changed CMakeLists.txt to only link CPU_XENONCAT

There were no issues during the build process:

+1, for me too (i7-4790K CPU).

[erknie]

Same problem for me on Xubuntu 16.04 with a gtx 1060 3GB card.

[k1-801]

Same problem. Arch linux, Intel Atom, running on CPU.

[suprnurd]

Darn. I was hoping there would be a solution here!

[tiferrei]

Same problem here. @huysamen have you been able to figure out what's going on here?

[calvintam236]

Same problem here.. 1070FE. I ran the benchmark inside docker

$ docker run --rm --device /dev/nvidia0:/dev/nvidia0 --device /dev/nvidiactl:/dev/nvidiactl --device /dev/nvidia-uvm:/dev/nvidia-uvm --device /dev/nvidia-modeset:/dev/nvidia-modeset calvintam236/nheqminer:nvidia -b

[romka1977]

This helped me, at least for actual mining (CPU-only mining)

in CMakeLists.txt

option(USE_CPU_TROMP "USE CPU_TROMP" ON) option(USE_CUDA_TROMP "USE CUDA_TROMP" OFF) option(USE_CPU_XENONCAT "USE CPU_XENONCAT" OFF) option(USE_CUDA_DJEZO "USE CUDA_DJEZO" OFF)

[Ahmad-Drak]

did anyone find a solution for this by any chance?

[klaxian]

Enabling only USE_CPU_TROMP does not solve the problem for me. Should we assume this will not be fixed?

Looks like this project is dead. I have gotten kost's fork to run, but it's of limited use: https://github.com/kost/nheqminer
