Practical tip: implement a lightweight health endpoint or admin socket that returns runtime stats (active tasks, pool usage, queued events).
To understand the value of hxcore.ol, we must look back at the limitations of symmetric multiprocessing (SMP). For decades, CPUs assumed all cores were identical. However, with the advent of ARM’s big.LITTLE and Intel’s Thread Director, hardware became asymmetric. The problem? Operating systems remained largely symmetrical in their logic. hxcore.ol
Early hybrid architectures suffered from "thread migration storms"—where critical processes were constantly shuffled between core types, causing cache invalidation and latency spikes. hxcore.ol was developed as a response to these inefficiencies. It acts as a traffic cop with predictive capabilities, ensuring that a video encoding thread stays on a performance core while a background telemetry service remains locked to an efficiency core.

| Aspect | Description |
|--------|-------------|
| Package name | hxcore.ol (Object‑Layer) |
| Primary purpose | Provides a lightweight, zero‑copy, memory‑mapped object model that abstracts raw buffers, hierarchical structures, and typed data into a uniform API. |
| Key design goals | - Zero‑copy (direct view onto memory‑mapped files or shared buffers)
- Deterministic memory layout (C‑compatible, little‑/big‑endian aware)
- Extensible type system (primitives, containers, custom structs)
- Thread‑safe, lock‑free reads
- Pluggable serialization (binary, JSON, protobuf, custom) |
| Typical use‑cases | • High‑frequency trading data feeds
• Scientific simulation snapshots
• Large‑scale telemetry ingestion
• In‑memory OLAP cubes
• Real‑time ML feature stores |
| Supported languages | Python (C‑extension), C++, Rust (via FFI), Java (JNI wrapper). The Python package ships a compiled binary hxcore.ol that calls into the C++ core. |
| Version | hxcore.ol >= 2.4.1 (current stable) |
