A Multi GPU Miner is Available for Ubuntu!


#41

And then you install the package you did build presumably?

Could you share the error message you get when it crashes (in log/epoch.log most likely)?


#42

hope this is somewhat helping

Ah :man_facepalming:, sorry for not spotting immediately. You still have to have the field extra_args: "" it is mandatory even if you don’t need any extra arguments.


#45

YES that fixxed it!!
thanks bro!


#46

Great! Glad I could help!

Beware though that it does not perform just as well as we hoped… As discussed above there seem to be a bottleneck starting multiple miners :frowning:

Configuration error (validation_failed)


#50

I think your epoch.yaml file is not correctly indented (i.e. everything is written at the beginning of a line) - yaml-format is layout sensitive so for example the mining part should look like below. See https://github.com/aeternity/epoch/blob/master/docs/configuration.md for more examples.

sync:
  port: 3015

mining:
  cuckoo:
     miner:
      instances: 2
      executable: cuda29
      extra_args: ""
      edge_bits: 29

...

#51

Let me try and validate it looking at the examples mentioned. If I have any issues I will let you know.


#52

Please find my epoch.yaml file and and let me know I am running only one GPU


#53

I am getting following error while validating


#54

Hello I validated my epoch.yaml file and i started the node it says it is syncing. But how do I know that it is completely synced.

Does that mean its syncing.


#55

Hello,

I have followed the guide for installing multiple GPU for mining. When I run my node it show it sync done.


But my nvidia-smi shows the following and it is not mining

I am using 3 1060 3GB Nvidia GPU’s

Will some one help…


#56

Hello,

My nvidia-smi output is below. Can some one help?


#57

According to the multigpu guide it shows under processes as ./cuda29-multi but for me it just shows ./cuda29 and I do not know the status of the mining. Can some one help to resolve this issue?
Here is the epoch-yaml file screenshot

Do I need to make any changes


#58

The mining effort is logged in log/epoch_mining.log and log/epoch_pow_cuckoo.log check those files to see what is going on.

The 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
