Variables
- uint64_t CUpti_ActivityMemcpy2::bytes [inherited]
-
The number of bytes transferred by the memory copy.
- uint32_t CUpti_ActivityMemcpy2::contextId [inherited]
-
The ID of the context where the memory copy is occurring.
- uint8_t CUpti_ActivityMemcpy2::copyKind [inherited]
-
The kind of the memory copy, stored as a byte to reduce record size.
See also:
- uint32_t CUpti_ActivityMemcpy2::correlationId [inherited]
-
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.
- uint32_t CUpti_ActivityMemcpy2::deviceId [inherited]
-
The ID of the device where the memory copy is occurring.
- uint32_t CUpti_ActivityMemcpy2::dstContextId [inherited]
-
The ID of the context owning the memory being copied to.
- uint32_t CUpti_ActivityMemcpy2::dstDeviceId [inherited]
-
The ID of the device where memory is being copied to.
- uint8_t CUpti_ActivityMemcpy2::dstKind [inherited]
-
The destination memory kind read by the memory copy, stored as a byte to reduce record size.
See also:
- uint64_t CUpti_ActivityMemcpy2::end [inherited]
-
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.
- uint8_t CUpti_ActivityMemcpy2::flags [inherited]
- CUpti_ActivityKindCUpti_ActivityMemcpy2::kind [inherited]
-
The activity record kind, must be CUPTI_ACTIVITY_KIND_MEMCPY2.
- uint32_t CUpti_ActivityMemcpy2::pad [inherited]
-
Undefined. Reserved for internal use.
- void * CUpti_ActivityMemcpy2::reserved0 [inherited]
-
Undefined. Reserved for internal use.
- uint32_t CUpti_ActivityMemcpy2::srcContextId [inherited]
-
The ID of the context owning the memory being copied from.
- uint32_t CUpti_ActivityMemcpy2::srcDeviceId [inherited]
-
The ID of the device where memory is being copied from.
- uint8_t CUpti_ActivityMemcpy2::srcKind [inherited]
-
The source memory kind read by the memory copy, stored as a byte to reduce record size.
See also:
- uint64_t CUpti_ActivityMemcpy2::start [inherited]
-
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.
- uint32_t CUpti_ActivityMemcpy2::streamId [inherited]
-
The ID of the stream where the memory copy is occurring.
