Synaptic-Delta-Sync (SDS) 🚀

Synaptic-Delta-Sync (SDS) is a high-performance, production-grade infrastructure library designed for atomic, secure, and zero-downtime neural network weight updates.

In modern AI environments, updating models often requires a full restart, leading to service disruption. SDS bridges this gap by enabling hot-swapping of weights directly into live inference engines without stopping the process.

🏗️ Architecture Overview

The SDS pipeline is designed for modularity, speed, and integrity. The architecture separates weight extraction, cryptographic validation, and device-specific injection into distinct, highly optimized layers.

💎 Core Technical Pillars

• Atomic Injection & Zero-Downtime: SDS modifies model weights at the memory-pointer level using torch.no_grad(), ensuring zero-drop inference.
• Sparse Delta Engine: Reduces patch sizes from MBs to KBs using mathematical delta computation.
• Cryptographic Security: SHA-256 integrity handshake verifies every patch before application.
• Dual-Engine Performance: Optimized paths for both CPU (direct memory) and GPU (Async CUDA Streams).

📦 Quick Start

Installation

Clone the repository to your local workspace:

git clone [https://github.com/ANSH-GIT77/synaptic-delta-sync.git](https://github.com/ANSH-GIT77/synaptic-delta-sync.git)
cd synaptic-delta-sync

Basic Usage

The AtomicInjector class handles all the heavy lifting automatically:

from sds.core.injection import AtomicInjector
from sds.protocol.serializer import load_patch

# 1. Initialize engine
injector = AtomicInjector(model)

# 2. Load secure patch
delta, metadata, patch_hash = load_patch("updates.sds")

# 3. Apply patch
injector.apply_patch(delta, patch_hash=patch_hash)
