Detailed Description

template<typename Data>
class Pscf::DeviceArray< Data >

Dynamic array on the GPU device with aligned data.

This class wraps an aligned C array with elements of type Data that is allocated in GPU device global memory. All member functions may be called from the CPU host, but this class does not offer access to individual elements via the subscript operator, operator[].

A DeviceArray can have one of two different relationships with its underlying data. In case 1, the data are owned by this object, so the allocation and destruction of the C array are performed by this object. In case 2, this object is instead "associated" with a slice of an array owned by a different DeviceArray. If this is the case, this object is not responsible for allocation or destruction of the underlying C array, and merely acts as a reference to the slice of the other array to which it is associated.

operator=() [1/2]

template<typename Data >

DeviceArray< Data > & Pscf::DeviceArray< Data >::operator= ( const DeviceArray< Data > & other )

virtual

Assignment operator, assign from another DeviceArray<Data> array.

Performs a deep copy, by copying values of all elements from device memory to device memory.

This function will allocate memory if this (LHS) array is not allocated. If this is allocated, it must have the same dimensions as the RHS DeviceArray<Data>.

Parameters

other
