LevelZero.NET
Managed .NET wrapper for Intel Level Zero GPU compute, with a built-in SPIR-V kernel catalog for swarm optimization, spiking neural networks, and multi-objective algorithms.
Features
- Zero-config GPU access — discover and use Intel GPUs via Level Zero with a clean managed API
- Built-in SPIR-V kernels — pre-compiled kernels for 11 Intel GPU targets (Tiger Lake through Panther Lake)
- Kernel catalog — automatic device detection and kernel resolution with fallback chain
- Native shim embedding —
LevelZeroShim.dll/libLevelZeroShim.soextracted at runtime, no manual setup - High-level kernel wrappers —
FitnessKernel,PSOVelocityKernel,NeuronUpdateKernel,STDPKernel,NBodyKernel, and more
Installation
dotnet add package LevelZero.NET
Quick Start
using LevelZero;
// Check GPU availability
if (LevelZeroRuntime.IsAvailable())
{
var device = LevelZeroRuntime.GetDefaultDevice();
Console.WriteLine($"GPU: {device}");
// Load a SPIR-V module
byte[] spirv = KernelCatalog.GetKernel("fitness_eval");
using var module = device.LoadModule(spirv);
// Allocate shared memory and launch
using var buffer = device.AllocShared<float>(1024);
device.Launch(module, "fitness_eval", workItems: 1024);
}

Kernel Catalog
The KernelCatalog resolves SPIR-V binaries using this chain:
- Explicit file path
LEVELZERO_SPIRV_DIRenvironment variable- NuGet package content
- Embedded assembly resources
- Fallback to
tgllpdevice target
