Estou tentando entrar na mineração há algum tempo, mas parece que estou correndo para problemas sem fim com meu hardware. Eu tenho seguido estas instruções para a parte de mineração:
E estas instruções para a parte do kit de ferramentas NVIDIA CUDA:
Como você pode instalar o CUDA no Ubuntu 16.04?
Após várias tentativas, consegui instalar (com êxito) os drivers CUDA, com a seguinte saída no meu deviceQuery:
CUDA Device Query (Runtime API) version (CUDART static linking)

< Default (multiple host threads can use ::cudaSetDevice() with device simultaneously) >
deviceQuery, CUDA Driver = CUDART, CUDA Driver Version = 9.1, CUDA Runtime Version = 9.1, NumDevs = 1
Result = PASS
Como a última linha diz Result = PASS , presumi que a instalação foi um sucesso. Esta é minha nvidia-smi -a output

No entanto, quando executo ethminer -M -G , recebo a seguinte saída

Assuming 131072kB available aperture size.
May lead to reduced performance or incorrect rendering.

beignet-opencl-icd: no supported GPU found, this is probably the wrong opencl-icd package for this hardware
(If you have multiple ICDs installed and OpenCL works, you can ignore this message)
No GPU device with sufficient memory was found. Can't GPU mine. Remove the -G argument
Parece haver algumas pessoas encontrando problemas semelhantes, mas em nenhum lugar eu encontrei uma solução abrangente. Eu encontrei até agora esse cara:
Quem foi direcionado para uma solução, não consigo compreender totalmente:
Normalmente não é o único a perguntar, mas isso tem me incomodado há semanas. Eu apreciaria qualquer ajuda! Thx com antecedência e tenha um bom!
