struct CUpti_ActivityMemcpyPtoP4#
The activity record for peer-to-peer memory copies.
This activity record represents a peer-to-peer memory copy (CUPTI_ACTIVITY_KIND_MEMCPY2).
Public Members
-
CUpti_ActivityKind kind#
The activity record kind, must be CUPTI_ACTIVITY_KIND_MEMCPY2.
-
uint8_t copyKind#
The kind of the memory copy, stored as a byte to reduce record size.
See also
-
uint8_t srcKind#
The source memory kind read by the memory copy, stored as a byte to reduce record size.
See also
-
uint8_t dstKind#
The destination memory kind read by the memory copy, stored as a byte to reduce record size.
See also
-
uint8_t flags#
The flags associated with the memory copy.
See also
-
uint64_t bytes#
The number of bytes transferred by the memory copy.
-
uint64_t start#
The start timestamp for the memory copy, in ns.
A value of 0 for both the start and end timestamps indicates that timestamp information could not be collected for the memory copy.
-
uint64_t end#
The end timestamp for the memory copy, in ns.
A value of 0 for both the start and end timestamps indicates that timestamp information could not be collected for the memory copy.
-
uint32_t deviceId#
The ID of the device where the memory copy is occurring.
-
uint32_t contextId#
The ID of the context where the memory copy is occurring.
-
uint32_t streamId#
The ID of the stream where the memory copy is occurring.
-
uint32_t srcDeviceId#
The ID of the device where memory is being copied from.
-
uint32_t srcContextId#
The ID of the context owning the memory being copied from.
-
uint32_t dstDeviceId#
The ID of the device where memory is being copied to.
-
uint32_t dstContextId#
The ID of the context owning the memory being copied to.
-
uint32_t correlationId#
The correlation ID of the memory copy.
Each memory copy 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 copy.
-
void *reserved0#
Undefined.
Reserved for internal use.
-
uint64_t graphNodeId#
The unique ID of the graph node that executed the memcpy through graph launch.
This field will be 0 if memcpy is not done using graph launch.
-
uint32_t graphId#
The unique ID of the graph that executed this memcpy through graph launch.
This field will be 0 if the memcpy is not done through graph launch.
-
uint32_t channelID#
The ID of the HW channel on which the memory copy is occurring.
-
CUpti_ChannelType channelType#
The type of the channel.
