Struct CudaDeviceProperties
- Namespace
- DotCompute.Backends.CUDA.Types.Native
- Assembly
- DotCompute.Backends.CUDA.dll
Structure containing detailed properties and capabilities of a CUDA device. This structure matches the cudaDeviceProp structure from CUDA 12.x/13.x runtime.
public struct CudaDeviceProperties : IEquatable<CudaDeviceProperties>- Implements
- Inherited Members
Remarks
This structure provides comprehensive information about a CUDA device including memory limits, processing capabilities, architectural features, and supported functionality. The layout is explicitly defined to match the native CUDA structure.
IMPORTANT: CUDA 12.0+ added luid and luidDeviceNodeMask fields at offset 272-283, shifting all subsequent fields by 16 bytes. The size is 1008 bytes in CUDA 13.0.
