Technical Details

Overview​

Installation and System Requirements​

Users need to install the Iagon compute CLI application on their devices to participate in the Compute feature.

System requirements include:

  • Available Storage
  • CPU cores
  • Available memory
  • Virtualization support
  • Internet bandwidth
  • Publicly accessible IP

Evaluation Pass Criteria​

  • *Values are the minimum requirements *
  • For how values are calculated see benchmarking process described below.
  • CPU: 60 IPS(eps)
  • Memory Bandwidth: 45000 Mbps(Read), 40000 Mbps(Write)*
  • Storage Bandwidth:
    -- Sequential: 5000 Mbps (Read), 5000 Mbps(Write)
    -- Random: 300 Mbps (Read), 300 Mbps
  • Network:
    -- Ping: 100 ms (max)
    -- Bandwidth: 150 Mbps (Download/Read), 150 Mbps (Upload/Write)
    -- Latency: 100 ms (max)

** Please note that these are not final evaluation criteria, and may change.

Evaluation Process​

CPU​

Sysbench is employed to calculate events per second (EPS) as IPS metrics for the CPU. Sysbench CPU stress test is run to calculate 200000 max primes in single-threaded mode for a maximum of 10 seconds.

Memory​

Sysbench is used to measure read and write bandwidth. Sysbench memory test is run to test for both read and write of 20GB data in 1KB blocks for a maximum of 10 seconds in single-threaded mode.

Storage​

Fio is used to calculate sequential and random read/write bandwidth. Two fio jobs are executed for sequential and random read/write respectively with 1GB data in 4KB blocks for max 5 seconds.

Network​

It is similar to the calculation for storage nodes. For ping, we ping the nearest Cloudflare server for a minimum of 5 replies and take the average value. For bandwidth, we perform upload and download for 4 iterations; in each iteration we upload/download presets values of different byte sizes and calculate the average. For latency, we use average latency while performing upload/download for bandwidth calculation.

Running Tasks on Iagon compute nodes (Subscriber)​

Users can use Iagon Compute Service to run their compute task on the compute nodes. Process to run the task on the Iagon compute node:

  • Subscription: Users subscribe to the Compute service.
  • Task Submission: Users define and send tasks through the Compute App.
  • Security Check: Tasks are filtered by the Security Guard to discard malicious ones, then encrypted and forwarded to the Task Distributor.
  • Node Selection: Task Distributor selects a node based on user subscription, task requirements, and network availability, then sends the task.
  • Task Execution: Compute node acknowledges the request and Task Manager decrypts and executes the task. Result Delivery: Upon completion, task result is encrypted and sent back to the backend, then provided to the user.

Running a IAGON Compute Node (Provider)​

Anyone with the compute resource can join the Iagon Compute Service, given that the compute resource matches the minimum requirements set for running the node. One can follow the instructions to download and run node cli to evaluate the system performance for eligibility to run a compute node.

Register the Node First, the node provider should register the node. This can be done in two ways :

  • Using Node CLI: Node CLI binary is released, that the node providers can download on their system. Using this binary, they can evaluate and register.

During registration,

  • The system is evaluated by running different benchmarks. The Node Monitor service on the backend also tests if the node is accessible for an external network.
  • Once all the tests and evaluations are completed and the node has passed the criteria, the node gets registered and the provider gets the authorization key which is required at the next step and should be stored safely by the node provider. The provider needs to go to the provider section in the Iagon web app, add the auth key from the node, and stake the required amount to complete the registration.

VM Runtime Component​

Develop the VM runtime component responsible for:

  • Initializing lightweight operating systems
  • Virtualizing compute tasks

The Compute feature within the Iagon network provides users with the opportunity to contribute their device's computational resources and earn rewards. By monitoring system metrics, ensuring accurate measurement of compute data, and developing a robust VM runtime component, we aim to create a reliable and efficient compute solution for our users.

note

Work on Compute is in the early stages. Documentation may change and will be updated as we progress with the next features.
