ZeroCompute.Core 1.0.0

ZeroCompute

ZeroCompute is a lightweight, hardware-accelerated compute execution library for .NET with zero external dependencies. It bridges pure CPU SIMD acceleration with native Windows Direct3D 11 Compute Shaders via COM VTable P/Invoke, delivering high-throughput GPGPU and parallel math execution without requiring external CUDA or OpenCL installations.

🌟 Key Capabilities

• Unified Compute Abstraction (IComputeContext): Write algorithmic compute code once; dispatch seamlessly across multi-core CPU SIMD or Direct3D 11 hardware GPUs.
• Pure C# Direct3D 11 Dispatcher: Zero third-party C++ wrappers (no SharpDX, no Silk.NET, no Vortice). Calls DirectX COM VTable methods directly with zero marshalling overhead.
• Hardware Fallback Strategy: Automatically detects dedicated GPU hardware (NVIDIA, AMD, Intel); falls back to high-speed vectorized CPU multi-threading if running in a headless or VM environment.
• Structured Buffers & DMA Transfer: High-speed host $\leftrightarrow$ device DMA transfers with staging readback buffers, unordered access views (UAV), and shader resource views (SRV).
• Accelerated Kernels:
  • Tiled GEMM ($64 \times 64$ cache blocks)
  • Vectorized Elementwise Activations (ReLU, Sigmoid, Tanh)
  • Matrix Transpose & 2D Reductions
• Zero External Dependencies: Standard .NET runtime only.

📦 Installation

Install via the .NET CLI:

dotnet add package ZeroCompute.Core

🚀 Quick Start

1. Unified Compute Context Selection

using ZeroCompute.Core;

// Select best available hardware: GPU if available, else CPU SIMD
using var context = ComputeDevice.GetBestDevice();

Console.WriteLine($"Active Compute Device: {context.DeviceName} (IsGpu: {context.IsGpu})");

2. High-Performance Matrix Multiplication

using ZeroTensor.Core;
using ZeroCompute.Core;

var a = Tensor.RandomUniform(1024, 1024);
var b = Tensor.RandomUniform(1024, 1024);

using var ctx = ComputeDevice.Cpu(); // Or ComputeDevice.Gpu()
var c = ctx.Gemm(a, b);

Console.WriteLine($"Result shape: [{c.Shape[0]}, {c.Shape[1]}]");
