Distribute your workload to the edge.
Nebulark is a distributed computing system for the browser built on WebAssembly for compute, WebRTC for networking and IPFS for storage.
The system is made up of the following components:
- Nebulark: The distributed computing system as a whole
- Ion: A compute, network and storage node of the network, running in the browser
- Nebula: A cluster of ions
- Spark: An app running on Nebulark
- Mission Control: A cluster and spark scheduling management interface
While all WebAssembly binaries are supported in theory, we support the following languages and toolchains using a Tier system:
| Tier Name | Exports Support | WASI | Mainstream Adoption |
|---|---|---|---|
| 1A | Yes | Yes (Vanilla) | Yes |
| 1B | Yes | Yes (Vanilla) | No |
| 2A | Yes | Yes (Extended) | No |
| 2B | Yes | No (Custom) | No |
The current implementation status:
| Tier | Language | Toolchain | Simple Calculator Spark | JSON Calculator Spark |
|---|---|---|---|---|
| 1A | C | clang | x | x |
| 1A | C++ | clang | x | x |
| 1A | Rust | rustup | x | x |
| 1B | AssemblyScript | asc | x | x |
| 1B | Zig | Zig | x | x |
| 2A | Go | TinyGo | x | x |
| 2B | Java | TeaVM | x | x |
See the examples for more concrete implementations or visit nebulark.space/examples/compute to try them out in your browser.
Basic full-duplex peer-to-peer networking support without the need for a signaling server already works, however the latter will be added in the future to ease the initial connection process. Take a look at the example code or visit nebulark.space/examples/networking to try it out in your browser.
Nebulark includes a discovery mechanism for nodes in order to simplify the SDP exchange for the networking stack. The implementation is heavily based on IPFS PubSub and the underlying libp2p stack and can already automatically connect peers in a room and broadcast messages, which can be used to distributed SDP information in the future. Take a look at the example code or visit nebulark.space/examples/discovery to try it out in your browser.
The default WebRTC star in use by default (/dns4/wrtc-star2.sjc.dwebops.pub/tcp/443/wss/p2p-webrtc-star) is a public testing server, which might be under heavy load and thus take 30+ seconds to broadcast new node information. For much better performance, please consider self-hosting and replacing the multiaddr with /ip4/127.0.0.1/tcp/13579/wss/p2p-webrtc-star, where 127.0.0.1 is the host and 13579 is the port of the self-hosted instance.
IPFS Mutable Filesystem is planned to be used in the future, but this is still in the concept phase.
Just visit nebulark.space; all modern browsers (Chrome, Firefox, Safari) are supported. Currently, there are just some examples, but as we continue development you'll be able to create and join a nebula, upload your sparks etc.
