Detailed Description

template<typename T>
struct limpet::TargetAllocator< T >

Allocator structure for dynamically allocating memory on multiple targets.

This tries to respect the standard C++ allocator trait as much as possible but is not yet used like one.

Definition at line 104 of file target.h.

Member Typedef Documentation

value_type

template<typename T>

typedef T limpet::TargetAllocator< T >::value_type

type to allocate

Definition at line 105 of file target.h.

Constructor & Destructor Documentation

TargetAllocator()

template<typename T>

limpet::TargetAllocator< T >::TargetAllocator ( Target  target, bool  always_managed = false  )

inline

Construct a TargetAllocator.

Parameters

target	target this allocator will allocate on
always_managed	if true, always use managed memory management for GPU targets

Definition at line 114 of file target.h.

Member Function Documentation

allocate()

template<typename T>

T* limpet::TargetAllocator< T >::allocate ( std::size_t  n, bool  do_zero = true  )

inline

Allocate memory for type T.

Parameters

n	number of objects of type T to allocate (size of the array)

Returns

a pointer to the allocated memory

Note

the allocated memory depends on this allocator's target, so using the returned pointer in the wrong context can result in an error (for example, dereferencing a GPU device pointer in CPU code)

Definition at line 154 of file target.h.

Here is the caller graph for this function:

deallocate()

template<typename T>

void limpet::TargetAllocator< T >::deallocate ( T *  ptr, std::size_t  n = 0  )

inline

Deallocate memory pointed by ptr.

Parameters

ptr	pointer to the memory to deallocate
n	size of the memory to deallocate. This is set to 0 by default because it isn't needed for the function to work, but is required to fit with the allocator trait interface.

Definition at line 250 of file target.h.

Here is the caller graph for this function:

get_target()

template<typename T>

Target limpet::TargetAllocator< T >::get_target ( ) const

inline

Get the target for this allocator.

Returns

this allocator's target

Definition at line 125 of file target.h.

set_target()

template<typename T>

void limpet::TargetAllocator< T >::set_target ( Target  new_target )

inline

Set a new target for this allocator.

Parameters

new_target

new target

Definition at line 134 of file target.h.
