End()

static void Rx::LFR::CCuda::End ( )

static

Finalizes CUDA. This finalizes all CUDA devices.

EnumerateCudaDevices()

static int Rx::LFR::CCuda::EnumerateCudaDevices ( )

static

Enumerates and stores all CUDA devices.

If a CUDA device is not recognized, it may be that it does not fulfill the minimum Compute Capability that is required by this runtime.

Returns

The number of available CUDA devices.

GC_Collect()

static void Rx::LFR::CCuda::GC_Collect ( )

static

Forces an immediate garbage collection of temporary CUDA memory.

GetDevice()

static const CCudaDevice& Rx::LFR::CCuda::GetDevice ( int  iIdx )

static

Gets a certain CUDA device.

Parameters

iIdx	[in] The index of the CUDA device. Must be in the range of [0, GetDeviceCount() - 1].

Returns

The CUDA device.

GetDeviceCount()

static int Rx::LFR::CCuda::GetDeviceCount ( )

static

Gets the number of available CUDA devices in your system. EnumerateCudaDevices has to be called at least once before.

Returns

The number of available CUDA devices.

GetDriverVersion()

static int Rx::LFR::CCuda::GetDriverVersion ( )

static

Gets the installed CUDA driver version. Returns 0 if there is no CUDA driver installed.

Returns

The driver version.

GetImpl() [1/2]

CCuda_Impl & Rx::LFR::CPimpl< CCuda_Impl , Interfaces::ECuda::ID >::GetImpl

inlineinherited

Gets the non constant implementation.

Returns

The implementation.

GetImpl() [2/2]

const CCuda_Impl & Rx::LFR::CPimpl< CCuda_Impl , Interfaces::ECuda::ID >::GetImpl

inlineinherited

Gets the constant implementation.

Returns

The implementation.

GetInterface() [1/2]

static void* Rx::LFR::CCuda::GetInterface ( Interfaces::ECuda::ID  eData )

static

Gets the interface defined by Interfaces::ECuda.

Parameters

eData

[in] The interface type.

Returns

Null if it fails, else the interface.

GetInterface() [2/2]

const void* Rx::LFR::CPimpl< CCuda_Impl , Interfaces::ECuda::ID >::GetInterface ( Interfaces::ECuda::ID  eInterface ) const

inherited

Gets the interface defined by the given interface ID.

Parameters

eInterface

[in] The interface ID.

Returns

Null if it fails, else the interface.

GetRuntimeVersion()

static int Rx::LFR::CCuda::GetRuntimeVersion ( )

static

Gets the installed CUDA runtime version.

Returns

The runtime version.

HasInterface()

bool Rx::LFR::CPimpl< CCuda_Impl , Interfaces::ECuda::ID >::HasInterface ( Interfaces::ECuda::ID  eInterface )

inlineinherited

Queries if this object has the given interface.

Parameters

eInterface

[in] The interface to query.

Returns

True if this class has the given interface, false if not.
