Detailed Description

template<typename T, class SVMTrait>
class cl::SVMAllocator< T, SVMTrait >

STL-like allocator class for managing SVM objects provided for convenience.

Note that while this behaves like an allocator for the purposes of constructing vectors and similar objects, care must be taken when using with smart pointers. The allocator should not be used to construct a unique_ptr if we are using coarse-grained SVM mode because the coarse-grained management behaviour would behave incorrectly with respect to reference counting.

Instead the allocator embeds a Deleter which may be used with unique_ptr and is used with the allocate_shared and allocate_ptr supplied operations.

Definition at line 4139 of file opencl.hpp.

◆ address() [2/2]

template<typename T , class SVMTrait >

◆ allocate()

template<typename T , class SVMTrait >
pointer cl::SVMAllocator< T, SVMTrait >::allocate ( size_type  size,
typename cl::SVMAllocator< void, SVMTrait >::const_pointer  = 0,
bool  map = true 
)
inline

Allocate an SVM pointer.

If the allocator is coarse-grained, this will take ownership to allow containers to correctly construct data in place.

Args &&...  args 
)
inline

Definition at line 4211 of file opencl.hpp.

template<typename T , class SVMTrait >
template<class U >
void cl::SVMAllocator< T, SVMTrait >::destroy ( U *  p)
inline

Definition at line 4217 of file opencl.hpp.

◆ max_size()

template<typename T , class SVMTrait >
size_type cl::SVMAllocator< T, SVMTrait >::max_size ( ) const
inlinenoexcept

Return the maximum possible allocation size. This is the minimum of the maximum sizes of all devices in the context.

Definition at line 4197 of file opencl.hpp.

◆ operator==()

template<typename T , class SVMTrait >
bool cl::SVMAllocator< T, SVMTrait >::operator== ( SVMAllocator< T, SVMTrait > const &  rhs)
inline

Returns true if the contexts match.
