itk::OpenCLPlatform Class Reference

#include <itkOpenCLPlatform.h>

Detailed Description

The OpenCLPlatform represent platform model for OpenCL.

The platform model consists of a host connected to one or more OpenCL devices. An OpenCL device is divided into one or more compute units (CUs) which are further divided into one or more processing elements (PEs). Computations on a device occur within the processing elements.

The GetAllPlatforms() function can be used to obtain the list of OpenCL platforms that are accessible to the host. For each platform, OpenCLDevice::GetDevices() can be used to get devices with different capabilities under a single platform.

Member Function Documentation

GetAllPlatforms()

static std::list< OpenCLPlatform > itk::OpenCLPlatform::GetAllPlatforms ( )

static

Returns a list of all OpenCL platforms that are supported by this host.

GetExtensions()

std::list< std::string > itk::OpenCLPlatform::GetExtensions

(

)

const

Returns a list of the extensions supported by this OpenCL platform.

See also

HasExtension()

GetExtensionSuffix()

std::string itk::OpenCLPlatform::GetExtensionSuffix

(

)

const

Returns the vendor extension suffix for this platform if the {cl_khr_icd} extension is supported; an empty string otherwise.

GetName()

std::string itk::OpenCLPlatform::GetName

(

)

const

Returns the name of this OpenCL platform.

GetOpenCLVersion()

OpenCLVersion itk::OpenCLPlatform::GetOpenCLVersion

(

)

const

Returns the OpenCL versions supported by this platform.

See also

GetVersion(), OpenCLDevice::GetOpenCLVersion()

GetPlatform()

static OpenCLPlatform itk::OpenCLPlatform::GetPlatform ( const OpenCLPlatform::VendorType  vendor )

static

Returns a list of all OpenCL platforms that are supported by this host.

GetPlatformId()

cl_platform_id itk::OpenCLPlatform::GetPlatformId ( ) const

inline

Returns the native OpenCL platform identifier for this object.

Definition at line 77 of file itkOpenCLPlatform.h.

GetProfile()

std::string itk::OpenCLPlatform::GetProfile

(

)

const

Returns the profile that is implemented by this OpenCL platform, usually FULL_PROFILE or EMBEDDED_PROFILE.

See also

IsFullProfile(), IsEmbeddedProfile()

GetVendor()

std::string itk::OpenCLPlatform::GetVendor

(

)

const

Returns the name of the vendor of this OpenCL platform.

GetVendorType()

VendorType itk::OpenCLPlatform::GetVendorType

(

)

const

Returns the OpenCLPlatform::VendorType of the vendor of this OpenCL platform.

See also

OpenCLPlatform::VendorType

GetVersion()

std::string itk::OpenCLPlatform::GetVersion

(

)

const

Returns the OpenCL versions supported by this platform as string, usually something like {OpenCL 1.2}.

See also

GetOpenCLVersion()

HasExtension()

bool itk::OpenCLPlatform::HasExtension

(

const std::string &

name

)

const

Returns true if this platform has an extension called name, false otherwise. This function is more efficient than checking for name in the return value from GetExtensions(), if the caller is only interested in a single extension. Use extensions() to check for several extensions at once.

GetExtensions()

IsEmbeddedProfile()

bool itk::OpenCLPlatform::IsEmbeddedProfile

(

)

const

Returns true if profile() is EMBEDDED_PROFILE, false otherwise.

See also

IsFullProfile()

IsFullProfile()

bool itk::OpenCLPlatform::IsFullProfile

(

)

const

Returns true if profile() is FULL_PROFILE, false otherwise.

See also

IsEmbeddedProfile()

IsNull()

bool itk::OpenCLPlatform::IsNull ( ) const

inline

Returns true if this OpenCL platform identifier is null.
