From allocation to orchestration.

EchoCore Memory is an open source AGPL 3.0+ memory orchestration system for Linux designed to transform how operating systems manage RAM under real-world workloads. Instead of relying entirely on passive allocation and reclaim behavior, EchoCore Memory introduces a modular intelligence layer that actively monitors, prioritizes, predicts, and coordinates memory usage across the entire system. The project is built around the idea that memory should be treated as a scheduled and policy-driven resource, similar to how modern operating systems schedule CPU time.

At the core of EchoCore Memory is the Memory Priority Scheduler, a system that assigns applications and services to dynamic memory priority classes. Rather than allowing all processes to compete equally during periods of pressure, the scheduler determines which applications should retain memory, which can safely compress or shrink, and which should be reclaimed first. This approach helps improve responsiveness during multitasking, development workloads, gaming sessions, container usage, and high-memory AI or server environments.

EchoCore Memory also includes an Adaptive Swap Strategy Engine that transforms swap from a static fallback mechanism into a dynamic performance layer. The engine continuously adjusts swap aggressiveness, compression behavior, and ZRAM usage based on live system conditions, workload modes, and process priorities. Combined with the optional AI-Based Memory Prediction Engine, EchoCore Memory can anticipate memory spikes before they occur, enabling proactive reclaiming, compression, and balancing strategies that reduce slowdowns and improve system stability.

Another major feature is the per-application memory profile system. Applications can be assigned configurable memory behaviors such as soft and hard memory limits, swap sensitivity, compression eligibility, idle decay policies, and foreground priority boosts. These profiles allow systems to adapt differently for browsers, development tools, servers, games, AI workloads, and background services. EchoCore Memory also supports global Workload Modes that instantly change how the entire memory system behaves, including Performance Mode, Balanced Mode, Gaming Mode, Power Saver Mode, AI Workload Mode, and Server Mode.

The entire platform is designed with modularity as a foundational principle. All major subsystems communicate through an event bus architecture, allowing modules to remain independent, replaceable, and extensible. This makes EchoCore Memory suitable for experimentation, community-developed extensions, and future expansion into broader system resource orchestration. Rather than replacing the Linux kernel’s memory manager, EchoCore Memory operates as a coordinated orchestration layer that enhances visibility, predictability, and control over modern memory behavior.
