Testing the First GPU Grid for AI Inference
The first phase of the Nosana Test Grid has concluded. We want to give a big shout-out to everyone involved and who contributed! During these weeks, many components of the Nosana GPU grid were put to the test. Over a hundred GPU nodes managed to connect and were assigned to various AI-inference workloads, benchmarks, and other tasks over six weeks. This has provided us with valuable input for the development of the network and has marked the way forward.
In this article, we will summarize the key achievements, insights gained, and future improvements identified during the inaugural phase of the Nosana Test Grid, shedding light on the successful onboarding process, diverse AI-inference workloads, and the invaluable feedback received from participants that will guide us in enhancing the Nosana network for its next phase.
Test Grid Goals
The Test Grid was the first public GPU grid on the Nosana network, and an essential part of the process was establishing how nodes are identified, selected, and assigned to the grid. Nosana is committed to enabling underutilized consumer hardware and is designed to support a wide variety of hardware owned by semi-technical users. This means that we consider the onboarding process to be an essential part of the project. To provide personal assistance and process all feedback promptly, the number of Test Grid nodes was capped at 110. The selection included a wide range of device types and a good geographical distribution.
Onboarding Process
During the first stop in the Test Grid application, users had to download the Nosana Node software, follow the node configuration guide, run a benchmark job, and use the results to submit the Test Grid application form. A total of 442 nodes went through this process and provided an abundance of feedback. During onboarding, we accomplished the following:
- Complete support for both Windows and Linux-based nodes
- Connected nodes from 47 different countries
- A total of 22 different GPU models were connected
- The majority of users rated the experience as “Smooth as butter”
The team has collected all feedback and will release an updated guide and video tutorial based on this. From the total onboarded nodes, a selection of 112 users was made, and they received an access NFT that activated their nodes. To properly test various use cases, participants were divided into Test Grid Markets based on their GPU model.
Nosana Explorer
Nosana has released an interface to inspect the Test Grid in detail: https://explorer.nosana.io. This enables anyone to look ‘behind the scenes’ of the Nosana test grid, revealing real-time data and statistics. This interface is crucial for our team, as it enhances transparency with our community and users, providing a deeper understanding of the Test Grid’s operations.
AI Inference Workloads
The Test Grid was divided into 13 compute markets of devices with similar specifications. These markets are continuously filled with a variety of GPU compute jobs. The majority of the AI workloads were targeted at image generation tasks using Stable Diffusion and speech recognition tasks using Whisper. Some jobs mimicked production workloads, while others aimed at stress testing and benchmarking the network to its limits. Here’s an overview of the number of jobs that were run:
Successful jobs: 139,749 Total job duration: 35,773.7 hours (or 1,490.6 days) Audio hours transcribed: 158,260.3 hours (or 6,594.2 days) Images generated: 935,097
Future Improvements
Over 300 Discord tickets were raised and addressed throughout the Test Grid. As the Test Grid concluded, participants submitted feedback forms, and our team organized a Discord Live session to delve deeper into discussions on additional feedback. Undoubtedly, these interactions have been the most valuable aspects of our experience.
-
Making the network more robust During the Test Grid, there were cases where compute jobs could not be finalized due to external factors. The causes ranged from malfunctioning RPC nodes and congestion on Solana to GPU reliability. The Nosana software will be adapted to be more resilient when finalizing executed compute jobs, so nodes will not miss out on payments.
-
Allow more flexible GPU setups At several occasions, participants requested more flexibility when it comes to upgrading and switching GPUs. Some users with advanced multi-GPU setups could only contribute one GPU at a time. Others upgraded their GPU to maximize income or wanted to switch between different GPU models during the day. We intend to support all these scenarios in future versions of Nosana.
Next Steps
The nodes currently connected to the Test Grid can keep running workloads and will continue to receive $NOS rewards. Nodes on the waitlist should keep an eye on their inbox, as the onboarding process is progressing gradually. In the meantime, the Nosana team is preparing for Phase 2 of the Test Grid. During this phase, job diversity will increase, allowing end-users to run actual workloads on the network.
