Database-Native OS (manster 0.1)

Bare-metal
efficiency.

We built a custom x86_64 kernel in Rust to eliminate OS overhead. Direct hardware control for high-concurrency database workloads.

Internal Architecture

A kernel designed solely for data.

Direct-to-Hardware Serial I/O

COM1 UART 16550A driver for zero-latency kernel debugging and system monitoring.

Rust Memory Safety

Physical frame allocator and heap management built with 100% memory-safe Rust code.

Multiboot2 Protocol

Custom boot sequence that enters 64-bit long mode directly via GRUB for maximum control.

[boot] Initializing manster subsystems...

INFO: Serial I/O initialized [COM1]

INFO: GDT & Long Mode entered

INFO: Physical Frame Allocator ready

WAL: Ring buffer initialized at 0x100000

READY: Kernel taking control (kernel_main)

_

Purpose-built instances.

Each node runs on its own isolated kernel instance for peak performance.

Vector-X1 Engine

Hardware-accelerated vector similarity search. Directly uses CPU SIMD instructions through the bare-metal kernel.

Write-Ahead Logging (WAL)

Transaction-based crash recovery with LSN-based replay integrated into the kernel storage layer.

Worker Scheduler

Dedicated worker pool architecture for concurrent task execution without context switching.

Bare-Metal Safety

No OS overhead. Direct hardware control for predictable and safe data processing.

Deterministic State

Reproducible task scheduling and state management for distributed systems.
