Cuckoo Cycle GPU memory requirements

tromp · December 1, 2018, 6:14pm

With the default -E 0, the GPU mean miner for 2^29 edges requires 7 GB.
With option -E 1 this drops to 5 GB along with a slight slowdown.
With option -E 2 it drops to the minimum of 3.5 GB with slightly more slowdown.

If the memory is 3GB what arguments should I give? Because I am using 1060 3GB GPU’s

I don’t see a way to efficiently GPU mine with only 3 GB.

Thanks. So you mean I cannot mine aeternity with 3GB cards. So is there any tweak to mine with 3GB i have 140 cards

With 3GB cards, you cannot mine aeternity efficiently.
There’s no tweak I can think of.

Do you think it is possible to make a lean executable that works on arm? as to be running an aeternity node on pi3/tinkerboard.

I know there is a specific x86 library that is nto available for the mean/lean executable.

It’s possible, but a single graph will take minutes on a pi3; so most of your efforts will be wasted…

Kryztoval · December 1, 2018, 10:57pm

I don’t want it to mine, just to be able to sync and verify.

I understand a single graph in a raspberry pi3 would take a long long time (too little ram, not enough cpu power).

Hello, Mr., my rig runs often with the screenshot reply. In the last second, the GPU load was very low, and the load reached 100% in the next second. Is this a normal working state? I use the -E 1 option, 6*1066. Thanks for any help!

You’re bound to see inefficiencies when the solver is used in the wrong way; see https://forum.aeternity.com/t/expected-1080-ti-performance

Btczuma · December 2, 2018, 12:39pm

Sorry,sir.I read the content of this topic. But I can’t fully understand it. Is it necessary to compile a new miner with the latest released code? Then put it in the epoch directory?

Btczuma · December 2, 2018, 12:39pm

Or just need to modify some configurations?

tromp · December 2, 2018, 12:58pm

You need to wait for AE devs to release new code that interfaces to my solver the proper way (preserving the solver context from nonce to nonce).

doge · December 2, 2018, 1:07pm

Can you pinpoint where in the grin repo you have provided the function call to the solver ?

Btczuma · December 2, 2018, 1:22pm

Got it, thank you.Continue to wait until the new release

tromp · December 2, 2018, 1:28pm

See Search · run_solver · GitHub

Where do these E options go??? In the epoch.yaml??? Like this???
cuckoo:
miner:
executable: cuda29
extra_args: “-E 0”
instances: 2
edge_bits: 29
hex_encoded_header: true
miner:
edge_bits: 29
executable: mean29-avx2
extra_args: -t 26

Yes, but you can’t mix CPU mining with GPU mining at the moment. So only one set of miner: configuration options is allowed…
