8spored

8spored is an open-source framework for building parallel and distributed data-processing applications. It introduces the concept of spores, small, isolated units of computation that can be serialized and transported between threads, processes, or machines.

Core idea: A spore encompasses a function and its captured state, while avoiding unrestricted access to global state to improve safety and determinism. Spores are executed inside spore containers, which provide an execution context, local memory, and I/O bindings.

Architecture: The framework includes a scheduler that maps spores to worker pools using strategies such as work-stealing and priority-based scheduling. Communication between components is achieved through a lightweight message-passing interface that supports backpressure and fault isolation.

Features: Lightweight serialization, language bindings for major ecosystems, pluggable backends (CPU, GPU, FPGAs), streaming pipelines, built-in observability, and deterministic execution modes for testing.

Origin and reception: The project was started by an international community of developers in the late 2010s. It emphasizes portability, safety, and composability. It has been adopted in research projects and some industry pilots focusing on data processing and simulations.

Usage: Developers create spores from functions, optionally capturing state, then deploy them into spore containers managed by the scheduler. Results are retrieved via futures or promises. The framework supports functional-style pipelines and streaming workflows.
