# 6.64. CUpti_ActivityMemoryPool2

struct CUpti_ActivityMemoryPool2

  The activity record for memory pool.

  This activity record represents a memory pool creation, destruction and trimming (CUPTI_ACTIVITY_KIND_MEMORY_POOL). This activity record provides separate records for memory pool creation, destruction and trimming operations. This allows to correlate the corresponding driver and runtime API activity record with the memory pool operation.

  Public Members

  CUpti_ActivityKind kind

    The activity record kind, must be CUPTI_ACTIVITY_KIND_MEMORY_POOL.

  CUpti_ActivityMemoryPoolOperationType memoryPoolOperationType

    The memory operation requested by the user, CUpti_ActivityMemoryPoolOperationType.

  uint64_t releaseThreshold

    The release threshold of the memory pool.

    `releaseThreshold` is valid for CUPTI_ACTIVITY_MEMORY_POOL_TYPE_LOCAL, CUpti_ActivityMemoryPoolType.

  uint64_t timestamp

    The start timestamp for the memory operation, in ns.

  uint64_t utilizedSize

    The utilized size of the memory pool.

    `utilizedSize` is valid for CUPTI_ACTIVITY_MEMORY_POOL_TYPE_LOCAL, CUpti_ActivityMemoryPoolType.
