Struct CudaDevResourceSnapshot

Namespace

JYPPX.CudaSharp

Assembly

JYPPX.CudaSharp.dll

Pointer-free copy of the observable fields in a CUDA device resource. CUDA 设备资源可观察字段的无指针复制快照。

public readonly struct CudaDevResourceSnapshot : IEquatable<CudaDevResourceSnapshot>

Implements

IEquatable<CudaDevResourceSnapshot>

Inherited Members

object.Equals(object, object)

object.GetType()

object.ReferenceEquals(object, object)

Remarks

CUDA keeps internal padding, opaque workqueue state, and a linked-resource pointer inside cudaDevResource. This snapshot intentionally never exposes or reuses those fields; it is suitable for capability and partition-planning diagnostics only. CUDA 在 cudaDevResource 内维护内部填充、opaque workqueue 状态和链式资源指针； 此快照有意不暴露或复用这些字段，只适合能力与分区规划诊断。
