Constructor Detail

CUpti_ActivitySynchronization2

public CUpti_ActivitySynchronization2()

Default native constructor.

CUpti_ActivitySynchronization2

public CUpti_ActivitySynchronization2(long size)

Native array allocator. Access with Pointer.position(long).

CUpti_ActivitySynchronization2

public CUpti_ActivitySynchronization2(Pointer p)

Pointer cast constructor. Invokes Pointer(Pointer).

Method Detail

position

public CUpti_ActivitySynchronization2 position(long position)

Overrides:

position in class Pointer

getPointer

public CUpti_ActivitySynchronization2 getPointer(long i)

Overrides:

getPointer in class Pointer

kind

@Cast(value="CUpti_ActivityKind")
public int kind()

The activity record kind, must be CUPTI_ACTIVITY_KIND_SYNCHRONIZATION.

kind

public CUpti_ActivitySynchronization2 kind(int setter)

type

@Cast(value="CUpti_ActivitySynchronizationType")
public int type()

The type of record.

type

public CUpti_ActivitySynchronization2 type(int setter)

start

@Cast(value="uint64_t")
public long start()

The start timestamp for the function, in ns. A value of 0 for both the start and end timestamps indicates that timestamp information could not be collected for the function.

start

public CUpti_ActivitySynchronization2 start(long setter)

end

@Cast(value="uint64_t")
public long end()

The end timestamp for the function, in ns. A value of 0 for both the start and end timestamps indicates that timestamp information could not be collected for the function.

end

public CUpti_ActivitySynchronization2 end(long setter)

correlationId

@Cast(value="uint32_t")
public int correlationId()

The correlation ID of the API to which this result is associated.

correlationId

public CUpti_ActivitySynchronization2 correlationId(int setter)

contextId

@Cast(value="uint32_t")
public int contextId()

The ID of the context for which the synchronization API is called. In case of context synchronization API it is the context id for which the API is called. In case of stream/event synchronization it is the ID of the context where the stream/event was created.

contextId

public CUpti_ActivitySynchronization2 contextId(int setter)

streamId

@Cast(value="uint32_t")
public int streamId()

The compute stream for which the synchronization API is called. A CUPTI_SYNCHRONIZATION_INVALID_VALUE value indicate the field is not applicable for this record. Not valid for cuCtxSynchronize, cuEventSynchronize.

streamId

public CUpti_ActivitySynchronization2 streamId(int setter)

cudaEventId

@Cast(value="uint32_t")
public int cudaEventId()

The event ID for which the synchronization API is called. A CUPTI_SYNCHRONIZATION_INVALID_VALUE value indicate the field is not applicable for this record. Not valid for cuCtxSynchronize, cuStreamSynchronize.

cudaEventId

public CUpti_ActivitySynchronization2 cudaEventId(int setter)

cudaEventSyncId

@Cast(value="uint64_t")
public long cudaEventSyncId()

A unique ID to associate event synchronization records with the latest CUDA Event record. Similar field is added in CUpti_ActivityCudaEvent2 to associate synchronization record to the CUDA Event record. The same CUDA event can be used multiple times, so the event id will not be unique to correlate the synchronization record with the latest CUDA Event record. This field will be unique and can be used to do the required correlation. A CUPTI_SYNCHRONIZATION_INVALID_VALUE value indicates that the field is not applicable for this record. Valid only for synchronization records related to CUDA Events.

cudaEventSyncId

public CUpti_ActivitySynchronization2 cudaEventSyncId(long setter)

returnValue

@Cast(value="uint32_t")
public int returnValue()

The return value for the synchronization record. Use cuptiActivityEnableAllSyncRecords API to enable/disable collection of synchronization records with return value being non-zero. This will be a CUresult value.

returnValue

public CUpti_ActivitySynchronization2 returnValue(int setter)

pad

@Cast(value="uint32_t")
public int pad()

Undefined. Reserved for internal use.

pad

public CUpti_ActivitySynchronization2 pad(int setter)
