RamShared borrows idle GPU memory as a high-speed swap cushion on Linux & WSL2—without freezing your OS. Unlike naive GPU swap tools that crash during memory eviction, RamShared uses a crash-safe cascading tier: • zram (compressed RAM) • GPU VRAM (cushion) • NVMe (last resort) Features active latency canary monitoring, automatic page demotion, and Rust-native safety via ublk/NBD drivers to keep your machine responsive under heavy loads.
