This repository contains all the necessary files and functions to define Bittensor's Compute Subnet. It enables running miners on netuid 15 in Bittensor's test network or netuid 27 in Bittensor's main network.
This repository serves as a compute-composable subnet, integrating various cloud platforms (e.g., Runpod, Lambda, AWS) into a cohesive unit. Its purpose is to enable higher-level cloud platforms to offer seamless compute composability across different underlying platforms. With the proliferation of cloud platforms, there's a growing need for a subnet that can seamlessly integrate these platforms, allowing efficient resource sharing and allocation. This compute-composable subnet empowers nodes to contribute computational power, with validators ensuring the integrity and efficiency of the shared resources.
compute/protocol.py: Defines the wire-protocol used by miners and validators.neurons/miner.py: Defines the miner's behavior in responding to requests from validators.neurons/validator.py: Defines the validator's behavior in requesting information from miners and determining scores.

Prior to running a miner or validator, you must create a wallet and register the wallet to a netuid. Once you have done so, you can run the miner and validator with the following commands.

Miners contribute processing resources, notably GPU (Graphics Processing Unit) and CPU (Central Processing Unit) instances, to facilitate optimal performance in essential GPU and CPU-based computing tasks. The system operates on a performance-based reward mechanism, where miners are incentivized through a tiered reward structure correlated to the processing capability of their hardware. High-performance devices are eligible for increased compensation, reflecting their greater contribution to the network's computational throughput. Emphasizing the integration of GPU instances is critical due to their superior computational power, particularly in tasks demanding parallel processing capabilities. Consequently, miners utilizing GPU instances are positioned to receive substantially higher rewards compared to their CPU counterparts, in alignment with the greater processing power and efficiency GPUs bring to the network.
A key aspect of the miners' contribution is the management of resource reservations. Miners have the autonomy to set specific timelines for each reservation of their computational resources. This timeline dictates the duration for which the resources are allocated to a particular task or user. Once the set timeline reaches its conclusion, the reservation automatically expires, thereby freeing up the resources for subsequent allocations. This mechanism ensures a dynamic and efficient distribution of computational power, catering to varying demands within the network.
# To run the miner
cd neurons
python -m miner.py
--netuid <your netuid> # The subnet id you want to connect to
--subtensor.network <your chain url> # blockchain endpoint you want to connect
--wallet.name <your miner wallet> # name of your wallet
--wallet.hotkey <your miner hotkey> # hotkey name of your wallet
--logging.debug # Run in debug mode, alternatively --logging.trace for trace modeValidators hold the critical responsibility of rigorously assessing and verifying the computational capabilities of miners. This multifaceted evaluation process commences with validators requesting miners to provide comprehensive performance data, which includes not only processing speeds and efficiencies but also critical metrics like Random Access Memory (RAM) capacity and disk space availability.
The inclusion of RAM and disk space measurements is vital, as these components significantly impact the overall performance and reliability of the miners' hardware. RAM capacity influences the ability to handle large or multiple tasks simultaneously, while adequate disk space ensures sufficient storage.
Following the receipt of this detailed hardware and performance information, validators proceed to test the miners' computational integrity. This is achieved by presenting them with complex hashing challenges, designed to evaluate the processing power and reliability of the miners' systems. Validators adjust the difficulty of these problems based on the comprehensive performance profile of each miner, including their RAM and disk space metrics.
In addition to measuring the time taken by miners to resolve these problems, validators meticulously verify the accuracy of the responses. This thorough examination of both speed and precision, complemented by the assessment of RAM and disk space utilization, forms the crux of the evaluation process.
Based on this extensive analysis, validators update the miners' scores, reflecting a holistic view of their computational capacity, efficiency, and hardware quality. This score then determines the miner's weight within the network, directly influencing their potential rewards and standing. This scoring process, implemented through a Python script, considers various factors including CPU, GPU, hard disk, and RAM performance. The script's structure and logic are outlined below:
The scoring system has been updated, if you want to check the old hardware mechanism: Hardware scoring
The score calculation function determines a miner's performance based on various factors:
Successful Problem Resolution: It first checks if the problem was solved successfully. If not, the score remains at zero.
Problem Difficulty: This measures the complexity of the solved task. The code restricts this difficulty to a maximum allowed value.
Weighting Difficulty and Elapsed Time: The function assigns a weight to both the difficulty of the solved problem (75%) and the time taken to solve it (25%).
Exponential Rewards for Difficulty: Higher problem difficulty leads to more significant rewards. An exponential formula is applied to increase rewards based on difficulty.
Allocation Bonus: Miners that have allocated machine receive an additional bonus added to their final score.
Effect of Elapsed Time: The time taken to solve the problem impacts the score. A shorter time results in a higher score.
- Max Score = 1e5
- Score = Lowest Difficulty + (Difficulty Weight * Problem Difficulty) + (Elapsed Time * 1 / (1 + Elapsed Time) * 10000) + Allocation Bonus
- Normalized Score = (Score / Max Score) * 100
- Successful Problem Resolution: True
- Elapsed Time: 4 seconds
- Problem Difficulty: 6
- Allocation: True
Score = 8.2865
- Successful Problem Resolution: True
- Elapsed Time: 16 seconds
- Problem Difficulty: 8
- Allocation: True
Score = 24.835058823529412

-
Resource Requirement Analysis: The mechanism begins by analyzing the specific resource requirements of each task, including CPU, GPU, memory, and storage needs.
-
Miner Selection: Based on the analysis, the mechanism selects suitable miners that meet the resource requirements. This selection process considers the current availability, performance history, and network weights of the miners.
-
Dynamic Allocation: The allocation of tasks to miners is dynamic, allowing for real-time adjustments based on changing network conditions and miner performance.
-
Efficiency Optimization: The mechanism aims to maximize network efficiency by matching the most suitable miners to each task, ensuring optimal use of the network's computational power.
-
Load Balancing: It also incorporates load balancing strategies to prevent overburdening individual miners, thereby maintaining a healthy and sustainable network ecosystem.
Through these functionalities, the allocation mechanism ensures that computational resources are utilized efficiently and effectively, contributing to the overall robustness and performance of the network.
