Detailed Description

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.


Field Documentation

The virtual address of the allocation.

The number of bytes of memory allocated.

The ID of the context. If context is NULL, contextId is set to CUPTI_INVALID_CONTEXT_ID.

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.

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

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

The activity record kind, must be CUPTI_ACTIVITY_KIND_MEMORY2

The memory kind requested by the user, CUpti_ActivityMemoryKind.

The memory operation requested by the user, CUpti_ActivityMemoryOperationType.

The memory pool configuration used for the memory operations.

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

The program counter of the memory operation.

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

The ID of the stream. If memory operation is not async, streamId is set to CUPTI_INVALID_STREAM_ID.

The start timestamp for the memory operation, in ns.
