Properties

DeviceOrdinal

Gets the CUDA device ordinal. 获取 CUDA 设备序号。

public int DeviceOrdinal { get; }

Property Value

int

ReservedMemoryCurrentBytes

Gets bytes currently reserved by the CUDA graphs asynchronous allocator. 获取 CUDA graphs 异步分配器当前保留的字节数。

public ulong ReservedMemoryCurrentBytes { get; }

Property Value

ulong

ReservedMemoryHighBytes

Gets the high watermark of reserved graph-memory bytes. 获取 graph memory 保留字节数的峰值。

public ulong ReservedMemoryHighBytes { get; }

Property Value

ulong

UsedMemoryCurrentBytes

Gets bytes currently associated with CUDA graphs. 获取当前与 CUDA graphs 关联的字节数。

public ulong UsedMemoryCurrentBytes { get; }

Property Value

ulong

Methods

ToString()

Returns a compact graph-memory diagnostic string. 返回紧凑的 graph memory 诊断字符串。

public override string ToString()

Returns

string

ToSummary()

Converts this graph-memory snapshot into a compact pointer-free summary. 将当前 graph memory 快照转换为紧凑、无指针逃逸的摘要。

public CudaDeviceGraphMemorySummary ToSummary()

Returns

CudaDeviceGraphMemorySummary

Remarks

This method only reads copied scalar counters returned by cudaDeviceGetGraphMemAttribute. It does not expose native graph-memory allocator pointers and does not promote local diagnostics to runtime or package-consumer proof. 该方法只读取 cudaDeviceGetGraphMemAttribute 返回的已复制标量计数；不会暴露原生 graph memory allocator 指针，也不会将本地诊断晋级为 runtime 或 package-consumer proof。
