Thanks! Getting tired of waiting for the windows guide, looks like its ubuntu time

Hey I tried installing with the procedure that you mentioned when I am trying to validate the epoch.yaml file i am getting validation error.

If I validate my yaml file I am getting validation error

think some of the formatting got lost on medium.
Try copying the content of this file and then change the beneficiary

Thank you so much @TwenteMining for helping the community get into mining!
Building æternity together!!! :heart_eyes:

Best,

I failed to launch my node.
This dosen’t really help for me at least.

9

Give us more details on what went wrong @MiniLemmings

10

I think it has to do with the epoch.yaml file.
medium messes up the formatting.
correct format is found here

hello,chris! Follow your tutorial,sync of my epoch looks normal, but the load on the GPU is very low，only 15watt/per card. After checking the LOG file, I got the above content. Where is the configuration wrong? Please help me, thank you
My “epoch_pow_cuckoo.log” looks like this:

Hi,

Have you fixed the issue because I have similar issue but I am using 1060 3GB. If you find any solution please let me know.

14

I tried to update CUDA 10. It seems that the power consumption is still low, but there are no errors in the log. God knows if it is working properly.

Crash dump is being written to: erl_crash.dump…done

16

Just to clarify the following is cleary an error… Which is kind of hinted by including the string ERROR :wink:

17

Yes, this error disappeared when I upgraded cuda. At present, the rig can work without error, but the power is unstable. The previous second is 100%, and the last second is 1%. Nothing in 24 hours :frowning:

18

Your node must have a beneficiary configured… See: aeternity/configuration.md at master · aeternity/aeternity · GitHub

20

Yes, there are beneficiaries in my configuration. I am just confused about one thing: nvidia-smi shows that the GPU always reaches 100% utilization in a few seconds and then 0% utilization in a few seconds. This is a huge fluctuation, isn’t it? is this normal? Is there a better solution? Thank you

21

As have been noted in other Threads here, the current gpu/multi-gpu setup is too simplistic and thus inefficient, there is too much overhead and I guess that is why you see fluctuation in GPU utilization.
