Swaps a vector with another vector.
event swap(queue &exec_queue, std::int64_t n, T *x, std::int64_t incx, T *y, std::int64_t incy, const vector_class<event> &dependencies = {});
The USM version of swap supports the following precisions and devices.
T | Devices Supported |
---|---|
float | Host, CPU, and GPU |
double | Host, CPU, and GPU |
std::complex<float> | Host, CPU, and GPU |
std::complex<double> | Host, CPU, and GPU |
Given two vectors of n elements, x and y, the swap routines return vectors y and x swapped, each replacing the other.
y <- x, x <- y
The queue where the routine should be executed.
Number of elements in vector x.
Pointer to the input vector x. The array must be of size at least (1 + (n - 1)*abs(incx)). See Matrix and Vector Storage for more details.
Stride of vector x.
Pointer to the input vector y. The array must be of size at least (1 + (n - 1)*abs(incy)). See Matrix and Vector Storage for more details.
Stride of vector y.
List of events to wait for before starting computation, if any. If omitted, defaults to no dependencies.
Pointer to the updated array x, that is, the input vector y.
Pointer to the updated array y, that is, the input vector x.
Output event to wait on to ensure computation is complete.
