CreateOpenGLContext(Int32, CUCtxFlags)

As the normal context constructor has the same arguments, the OpenGL-constructor is private with inverse arguement order. It has to be called from a static method. Create a new instance of managed CUDA for a OpenGL-device.

OpenGL resources from this device may be registered and mapped through the lifetime of this CUDA context.

Declaration

public static CudaContext CreateOpenGLContext(int deviceId, CUCtxFlags flags)

Parameters

Type	Name	Description
System.Int32	deviceId	CUdevice to map this context to.
CUCtxFlags	flags	Context creation flags

Returns

Type	Description
CudaContext

DeviceCanAccessPeer(CudaContext)

Queries if a device may directly access a peer device's memory

Dispose()

Dispose

Declaration

public void Dispose()

Dispose(Boolean)

For IDisposable.

Note: If this instance created the wrapped CUcontext, it will be destroyed and can't be accessed by other threads anymore.

If this instance only was bound to an existing CUcontext, the wrapped CUcontext won't be destroyed.

Declaration

protected virtual void Dispose(bool fDisposing)

Parameters

Type	Name	Description
System.Boolean	fDisposing

EnablePeerAccess(CudaContext)

If both the current context (current to the calling thread) and peerContext are on devices which support unified addressing (as may be queried using GetDeviceInfo), then on success all allocations from peerContext will immediately be accessible by the current context. See \ref CUDA_UNIFIED for additional details.

Note that access granted by this call is unidirectional and that in order to access memory from the current context in peerContext, a separate symmetric call to ::cuCtxEnablePeerAccess() is required.

Returns ErrorInvalidDevice if DeviceCanAccessPeer(CudaContext) indicates that the CUdevice of the current context cannot directly access memory from the CUdevice of peerContext.

Throws ErrorPeerAccessAlreadyEnabled if direct access of peerContext from the current context has already been enabled.

Throws ErrorInvalidContext if there is no current context, peerContext is not a valid context, or if the current context is peerContext.

Declaration

public static void EnablePeerAccess(CudaContext peerContext)

Parameters

Type	Name	Description
CudaContext	peerContext	Peer context to enable direct access to from the current context

GetStreamPriorityRange(ref Int32, ref Int32)

Returns numerical values that correspond to the least and greatest stream priorities.

Returns in leastPriority and greatestPriority the numerical values that correspond to the least and greatest stream priorities respectively. Stream priorities follow a convention where lower numbers imply greater priorities. The range of meaningful stream priorities is given by [greatestPriority, leastPriority]. If the user attempts to create a stream with a priority value that is outside the meaningful range as specified by this API, the priority is automatically clamped down or up to either leastPriority or greatestPriority respectively. See ::cuStreamCreateWithPriority for details on creating a priority stream. A NULL may be passed in for leastPriority or greatestPriority if the value is not desired. This function will return '0' in both leastPriority and greatestPriority if the current context's device does not support stream priorities (see ::cuDeviceGetAttribute).

Declaration

public void GetStreamPriorityRange(ref int leastPriority, ref int greatestPriority)

Parameters

Type	Name	Description

ProfilerInitialize(String, String, CUoutputMode)

Initialize the profiling.

Using this API user can initialize the CUDA profiler by specifying the configuration file, output file and output file format. This API is generally used to profile different set of counters by looping the kernel launch. The configFile parameter can be used to select profiling options including profiler counters. Refer to the "Compute Command Line Profiler User Guide" for supported profiler options and counters.

Limitation: The CUDA profiler cannot be initialized with this API if another profiling tool is already active, as indicated by the exception ErrorProfilerDisabled.

Declaration

public static void ProfilerInitialize(string configFile, string outputFile, CUoutputMode outputMode)

Parameters

Type	Name	Description
System.String	configFile	Name of the config file that lists the counters/options for profiling.
System.String	outputFile	Name of the outputFile where the profiling results will be stored.
CUoutputMode	outputMode	outputMode

ProfilerStart()

Enable profiling.

Enables profile collection by the active profiling tool for the current context. If profiling is already enabled, then cuProfilerStart() has no effect.

cuProfilerStart and cuProfilerStop APIs are used to programmatically control the profiling granularity by allowing profiling to be done only on selective pieces of code.

Declaration

public static void ProfilerStart()

ProfilerStop()

Disables profile collection by the active profiling tool for the current context. If profiling is already disabled, then cuProfilerStop() has no effect.

cuProfilerStart and cuProfilerStop APIs are used to programmatically control the profiling granularity by allowing profiling to be done only on selective pieces of code.

Declaration

public static void ProfilerStop()

PushContext()

Push the CUDA context

Declaration

public void PushContext()

SetCacheConfig(CUFuncCache)

On devices where the L1 cache and shared memory use the same hardware resources, this sets through cacheConfig the preferred cache configuration for the current context. This is only a preference. The driver will use the requested configuration if possible, but it is free to choose a different configuration if required to execute the function. Any function preference set via SetCacheConfig(CUFuncCache) will be preferred over this context-wide setting. Setting the context-wide cache configuration to PreferNone will cause subsequent kernel launches to prefer to not change the cache configuration unless required to launch the kernel.

This setting does nothing on devices where the size of the L1 cache and shared memory are fixed.

Launching a kernel with a different preference than the most recent preference setting may insert a device-side synchronization point.

Declaration

public void SetCacheConfig(CUFuncCache cacheConfig)

Parameters

Type	Name	Description
CUFuncCache	cacheConfig

SetCurrent()

Binds this CUDA context to the calling CPU thread

Declaration

public void SetCurrent()

SetLimit(CULimit, SizeT)

Setting limit to value is a request by the application to update the current limit maintained by the context. The driver is free to modify the requested value to meet h/w requirements (this could be clamping to minimum or maximum values, rounding up to nearest element size, etc). The application can use GetLimit(CULimit) to find out exactly what the limit has been set to.

Setting each CULimit has its own specific restrictions, so each is discussed here:

Value	Restriction
StackSize	StackSize controls the stack size of each GPU thread. This limit is only applicable to devices of compute capability 2.0 and higher. Attempting to set this limit on devices of compute capability less than 2.0 will result in the error ErrorUnsupportedLimit being returned.
PrintfFIFOSize	PrintfFIFOSize controls the size of the FIFO used by the printf() device system call. Setting PrintfFIFOSize must be performed before loading any module that uses the printf() device system call, otherwise ErrorInvalidValue will be returned. This limit is only applicable to devices of compute capability 2.0 and higher. Attempting to set this limit on devices of compute capability less than 2.0 will result in the error ErrorUnsupportedLimit being returned.
MallocHeapSize	MallocHeapSize controls the size in bytes of the heap used by the ::malloc() and ::free() device system calls. Setting MallocHeapSize must be performed before launching any kernel that uses the ::malloc() or ::free() device system calls, otherwise ErrorInvalidValue will be returned. This limit is only applicable to devices of compute capability 2.0 and higher. Attempting to set this limit on devices of compute capability less than 2.0 will result in the error ErrorUnsupportedLimit being returned.
DevRuntimeSyncDepth	DevRuntimeSyncDepth controls the maximum nesting depth of a grid at which a thread can safely call ::cudaDeviceSynchronize(). Setting this limit must be performed before any launch of a kernel that uses the device runtime and calls ::cudaDeviceSynchronize() above the default sync depth, two levels of grids. Calls to ::cudaDeviceSynchronize() will fail with error code ::cudaErrorSyncDepthExceeded if the limitation is violated. This limit can be set smaller than the default or up the maximum launch depth of 24. When setting this limit, keep in mind that additional levels of sync depth require the driver to reserve large amounts of device memory which can no longer be used for user allocations. If these reservations of device memory fail, ::cuCtxSetLimit will return ErrorOutOfMemory, and the limit can be reset to a lower value. This limit is only applicable to devices of compute capability 3.5 and higher. Attempting to set this limit on devices of compute capability less than 3.5 will result in the error ErrorUnsupportedLimit being returned.
DevRuntimePendingLaunchCount	DevRuntimePendingLaunchCount controls the maximum number of outstanding device runtime launches that can be made from the current context. A grid is outstanding from the point of launch up until the grid is known to have been completed. Device runtime launches which violate this limitation fail and return ::cudaErrorLaunchPendingCountExceeded when ::cudaGetLastError() is called after launch. If more pending launches than the default (2048 launches) are needed for a module using the device runtime, this limit can be increased. Keep in mind that being able to sustain additional pending launches will require the driver to reserve larger amounts of device memory upfront which can no longer be used for allocations. If these reservations fail, ::cuCtxSetLimit will return ErrorOutOfMemory, and the limit can be reset to a lower value. This limit is only applicable to devices of compute capability 3.5 and higher. Attempting to set this limit on devices of compute capability less than 3.5 will result in the error ErrorUnsupportedLimit being returned.

Declaration

public void SetLimit(CULimit limit, SizeT value)

Parameters

Type	Name	Description
CULimit	limit	Limit to set
SizeT	value	Size in bytes of limit

SetSharedMemConfig(CUsharedconfig)

Sets the shared memory configuration for the current context.

On devices with configurable shared memory banks, this function will set the context's shared memory bank size which is used for subsequent kernel launches.

Changed the shared memory configuration between launches may insert a device side synchronization point between those launches.

Changing the shared memory bank size will not increase shared memory usage or affect occupancy of kernels, but may have major effects on performance. Larger bank sizes will allow for greater potential bandwidth to shared memory, but will change what kinds of accesses to shared memory will result in bank conflicts.

This function will do nothing on devices with fixed shared memory bank size.

The supported bank configurations are: - DefaultBankSize: set bank width to the default initial setting (currently, four bytes). - FourByteBankSize: set shared memory bank width to be natively four bytes. - EightByteBankSize: set shared memory bank width to be natively eight bytes.

Declaration

public void SetSharedMemConfig(CUsharedconfig config)

Parameters

Type	Name	Description
CUsharedconfig	config

Synchronize()

Blocks until the device has completed all preceding requested tasks. Throws a CudaException if one of the preceding tasks failed. If the context was created with the SchedAuto flag, the CPU thread will block until the GPU context has finished its work.
