source code can not be installed in linux(centos)

[s jj]

Hi everyone,

I have downloaded mumax3.10 in my centos, following all steps on the git.However, when I run the  executable file “mumax3” . It says 

No binary for GPU. Your nvidia driver may be out-of-date

My GPU is nvidia P2000,  NVIDIA-SMI 430.34       Driver Version: 430.34       CUDA Version: 10.0.

I think this hardware and driver fit this mumax version. In fact, when I use the pre-compiled version, it warks. I need to modify the source code, so I have to compile it.

So can anyone help me? Thanks very much

Hi,

Did you play with the CUDA_CC variable? If one uses the default value (3.0), one will not get this error. But if one uses the value CUDA_CC=70, one will get that error with your GPU. Your GPU has compute capability 6.1. Therefore it is not able to run with that CC.

Therefore it is better if you use:

export CUDA_CC=61

This can be observed in the cuda directory of your src. If the suffix of your ptx files is _70.ptx then that is the reason.

Best regards,

Felipe
