Discussion: Multiple Miner Bounties (Large Rewards)

aeternity-team · November 21, 2018, 10:48am

Hello everyone!

In order to level the playing field for miners worldwide, we are announcing several bounties dedicated to AE mining. What we need is:

Multi GPU miner for mining AE with rigs
Stratum miner for enabling pool mining
Mining optimization

Rewards are as follows:

20 000 CHF for a Multi GPU miner and a guide on how to set up and use it
20 000 CHF for the Stratum miner and a guide how to use it
25 000 CHF for improving the efficiency of the currently existing AE mining software

DEADLINE: November 26, 2018 | 11:59 PM CEST

Anyone willing to join the bounty needs to register by filling-in this short form.

If you have any questions, please add them below.

Best,
The AE team

Hi, where can I get information when I need some more or additional informations?

Have an error: Failed to add synced block 1: incorrect_pow
Sure it means incorrect_pow, but why?

my config:
mining:
autostart: true
beneficiary: “ak_k4qAqr2a7rBd5Wt3QJQCHH5NasWJpmyr1uUsUUvVLBsDUtwpu”
cuckoo:
miner:
executable: lean30
node_bits: 30
extra_args: “-t 39”
nice: 0

thx

found this mining executeable:
lean16 lean28 lean30 mean16s-avx2 mean16s-generic mean28s-avx2 mean28s-generic mean30s-avx2 mean30s-generic verify16 verify28 verify30

can we use all of them? Where can I find additional informations about them and the meaning?

Edit:
I they will change on next release! Is there not an other way to build in the executables?

hey @Zwilla great to hear from you!

You need to pick number of bits matching the testnet that you want to connect.

lean/mean/cuda/avxX are versions of implementation of the algorithm. Providing that bits for graph are the same, the solutions will get verified cross nodes.

Zwilla · November 22, 2018, 3:21pm

is there anywhere a list of testnet peers?
For 0.25.0 I found this:
aenode://pp_HdcpgTX2C1aZ5sjGGysFEuup67K9XiFsWqSPJs4RahEcSyF7X@sync.sdk-edgenet.aepps.com:3015

How can I check testnet bits, is there a way to use automatic the right executable?

Hope I understand right, you know Im stupid plain German, with the honour always to confuse the grammar

Example:
on testnet A - 30bits: we can use: lean30 mean30s-avx2 mean30s-generic ?

on testnet B - 16bits: we can use: lean16 mean16s-avx2 mean16s-generic ?

on testnet C - 28bits: we can use: lean28 mean28s-avx2 mean28s-generic ?

Can you post the current testnet peers, and the bits they are running on?

I leave the field node_bits empty - no delete the line and engine will select the default one, or do I have alway to set the node_bits field.

epoch check_config epoch.yaml

Does “-t 5” really mean cpu cores? If I have a cpu with 10 cores with 20 threads and want to use them all, do I use “-t 20”?

If I use: $ epoch attach how can I detach without shutting down the node?

right, please check the docs:

github.com

aeternity/aeternity/blob/master/docs/configuration.md

# Introduction

This document describes how to configure your Aeternity node installed using a release binary for joining a public network of nodes (e.g. testnet) knowing an initial network peer to join.

## User-provided configuration

The `aeternity` system supports user-provided parameters via a JSON- or YAML-formatted config file.

### File name and location
The format of the config file is determined from the file extension: `.json` for JSON, or `.yaml` for YAML.

The location of the file can be specified in a few different ways, in order of priority:

1. The OS environment variable `AETERNITY_CONFIG` contains a filename
2. The Erlang/OTP environment variable `-aecore config` contains a filename
3. A file named `aeternity.{yaml,json}` exists in `${HOME}/.aeternity/aeternity/`
4. A file named `aeternity.{yaml,json}` exists in `${AETERNITY_TOP}/`

If all above checks fail, no user configuration is applied.

This file has been truncated. show original

bottom section miner configuration.

Mind that we have a release today/tomorrow, so testnet may be impacted.

the lower the bits, the faster we get a solution. One can use such configs in private testnets for personal tests.

Zwilla · November 23, 2018, 11:10pm

how can I start multiple mining instances on the same machine? Is there a setting for?
If not, can I run epoch multiple instances?
If not how to do that? Sure changing the ports and what else is needed at moment?
Sure virtualise one physical machine into many’s may a solution, but can I share the db folder or not?

vlad.chain · November 24, 2018, 3:18pm

We announced the Multi GPU bounty in order to find a solution to the “one node, one GPU” issue. Currently the only way to mine with multiple GPUs is to run multiple epoch instances. @michalzee

Hey everyone,

We are very happy to announce that we just publish a Multi GPU configuration.
Find it here and start mining.

Best regards,
Albena

I have found a way, later more, because I have to learn some erlang lessons first. It’s quit easy without docker, without vm nor nothing of them, it is on …

doge · November 28, 2018, 8:24pm

@Zwilla so the multi_gpu branch doesn’t natively support several GPU ?

Also, running several nodes just like this also didn’ t seem like much of a hassle.

emin.chain · November 28, 2018, 8:58pm

The multi GPU miner bounty was successfully claimed. It was published on out GitHub repo. I’m closing this topic please create another thread for questions regarding the multi GPU miner.
