7.68. CUpti_ActivityMemory2

struct CUpti_ActivityMemory2

The activity record for memory.

This activity record represents a memory allocation and free operation (CUPTI_ACTIVITY_KIND_MEMORY2). This activity record provides separate records for memory allocation and memory release operations. This allows to correlate the corresponding driver and runtime API activity record with the memory operation.

Note: This activity record is an upgrade over CUpti_ActivityMemory enabled using the kind CUPTI_ACTIVITY_KIND_MEMORY. CUpti_ActivityMemory provides a single record for the memory allocation and memory release operations.

Public Members

CUpti_ActivityKind kind

The activity record kind, must be CUPTI_ACTIVITY_KIND_MEMORY2.

CUpti_ActivityMemoryOperationType memoryOperationType

The memory operation requested by the user, CUpti_ActivityMemoryOperationType.

CUpti_ActivityMemoryKind memoryKind

The memory kind requested by the user, CUpti_ActivityMemoryKind.

uint32_t correlationId

The correlation ID of the memory operation.

Each memory operation is assigned a unique correlation ID that is identical to the correlation ID in the driver and runtime API activity record that launched the memory operation.

uint64_t address

The virtual address of the allocation.

The base address of the memory pool.

uint64_t bytes

The number of bytes of memory allocated.

uint64_t timestamp

The start timestamp for the memory operation, in ns.

uint64_t PC

The program counter of the memory operation.

uint32_t processId

The ID of the process to which this record belongs to.

uint32_t deviceId

The ID of the device where the memory operation is taking place.

uint32_t contextId

The ID of the context.

If context is NULL, contextId is set to CUPTI_INVALID_CONTEXT_ID.

uint32_t streamId

The ID of the stream.

If memory operation is not async, streamId is set to CUPTI_INVALID_STREAM_ID.

const char *name

Variable name.

This name is shared across all activity records representing the same symbol, and so should not be modified.

uint32_t isAsync

isAsync is set if memory operation happens through async memory APIs.

uint32_t pad1

Undefined.

Reserved for internal use.

CUpti_ActivityMemoryPoolType memoryPoolType

The type of the memory pool, CUpti_ActivityMemoryPoolType.

uint32_t pad2

Undefined.

Reserved for internal use.

uint64_t releaseThreshold

The release threshold of the memory pool in bytes.

releaseThreshold is valid for CUPTI_ACTIVITY_MEMORY_POOL_TYPE_LOCAL, CUpti_ActivityMemoryPoolType.

union CUpti_ActivityMemory2::[anonymous]::[anonymous] pool

The size of the memory pool in bytes and the processID of the memory pool.

size is valid if memoryPoolType is CUPTI_ACTIVITY_MEMORY_POOL_TYPE_LOCAL, CUpti_ActivityMemoryPoolType. processId is valid if memoryPoolType is CUPTI_ACTIVITY_MEMORY_POOL_TYPE_IMPORTED, CUpti_ActivityMemoryPoolType.

struct CUpti_ActivityMemory2::[anonymous] memoryPoolConfig

The memory pool configuration used for the memory operations.
