Type Alias universal_ptr

template <typename T> using universal_ptr = thrust::system::__THRUST_DEVICE_SYSTEM_NAMESPACE::universal_pointer< T >; universal_ptr stores a pointer to an object allocated in memory accessible to both hosts and devices.

Algorithms dispatched with this type of pointer will be dispatched to either host or device, depending on which backend you are using. Explicit policies (thrust::device, etc) can be used to specify where an algorithm should be run.

universal_ptr has pointer semantics: it may be dereferenced safely from both hosts and devices and may be manipulated with pointer arithmetic.

universal_ptr can be created with universal_allocator or by explicitly calling its constructor with a raw pointer.

The raw pointer encapsulated by a universal_ptr may be obtained by either its get method or the raw_pointer_cast free function.

Note: universal_ptr is not a smart pointer; it is the programmer’s responsibility to deallocate memory pointed to by universal_ptr.

See:

• host_ptr For the documentation of the complete interface which is shared by universal_ptr.
• raw_pointer_cast

Functions

Function tls_disjoint_pool

template <typename Upstream,   typename Bookkeeper> _CCCL_HOST thrust::mr::disjoint_unsynchronized_pool_resource< Upstream, Bookkeeper > & tls_disjoint_pool(Upstream * upstream = NULL,   Bookkeeper * bookkeeper = NULL); Potentially constructs, if not yet created, and then returns the address of a thread-local disjoint_unsynchronized_pool_resource,

Template Parameters:

• Upstream the first template argument to the pool template
• Bookkeeper the second template argument to the pool template

Function Parameters:

• upstream the first argument to the constructor, if invoked
• bookkeeper the second argument to the constructor, if invoked

Function operator==

template <typename Pointer> _CCCL_HOST_DEVICE bool operator==(const memory_resource< Pointer > & lhs,   const memory_resource< Pointer > & rhs); Compares the memory resources for equality, first by identity, then by is_equal.

Function operator!=

template <typename Pointer> _CCCL_HOST_DEVICE bool operator!=(const memory_resource< Pointer > & lhs,   const memory_resource< Pointer > & rhs); Compares the memory resources for inequality, first by identity, then by is_equal.

Function get_global_resource

template <typename MR> _CCCL_HOST MR * get_global_resource(); Returns a global instance of MR, created as a function local static variable.

Template Parameters: MR: type of a memory resource to get an instance from. Must be DefaultConstructible.

Returns: a pointer to a global instance of MR.

Function tls_pool

template <typename Upstream,   typename Bookkeeper> _CCCL_HOST thrust::mr::unsynchronized_pool_resource< Upstream > & tls_pool(Upstream * upstream = NULL); Potentially constructs, if not yet created, and then returns the address of a thread-local unsynchronized_pool_resource,

Template Parameters: Upstream: the template argument to the pool template

Function Parameters: upstream: the argument to the constructor, if invoked
