## Detailed Description

## Macro Definition Documentation

## magma_copyvector

#define magma_copyvector | ( |  | n,
|  |  | elemSize,
|  |  | dx_src,
|  |  | incx,
|  |  | dy_dst,
|  |  | incy,
|  |  | queue )

Copy vector dx_src on GPU device to dy_dst on GPU device.

Elements may be arbitrary size. Type-safe versions set elemSize appropriately. With CUDA unified addressing, dx and dy can be on different GPUs.

This version synchronizes the queue after the transfer. See magma_copyvector_async() for an asynchronous version.

Parameters

  [in] | n | Number of elements in vector.
  [in] | elemSize | Size of each element, e.g., sizeof(double).
  [in] | dx_src | Source array of dimension (1 + (n-1))*incx, on GPU device.
  [in] | incx | Increment between elements of hx_src. incx > 0.
  [out] | dy_dst | Destination array of dimension (1 + (n-1))*incy, on GPU device.
  [in] | incy | Increment between elements of dy_dst. incy > 0.
  [in] | queue | Queue to execute in.

## magma_copyvector_async

#define magma_copyvector_async | ( |  | n,
|  |  | elemSize,
|  |  | dx_src,
|  |  | incx,
|  |  | dy_dst,
|  |  | incy,
|  |  | queue )

Copy vector dx_src on GPU device to dy_dst on GPU device.

Elements may be arbitrary size. Type-safe versions set elemSize appropriately. With CUDA unified addressing, dx and dy can be on different GPUs.

This version is asynchronous: it may return before the transfer finishes. See magma_copyvector() for a synchronous version.

Parameters

  [in] | n | Number of elements in vector.
  [in] | elemSize | Size of each element, e.g., sizeof(double).
  [in] | dx_src | Source array of dimension (1 + (n-1))*incx, on GPU device.
  [in] | incx | Increment between elements of hx_src. incx > 0.
  [out] | dy_dst | Destination array of dimension (1 + (n-1))*incy, on GPU device.
  [in] | incy | Increment between elements of dy_dst. incy > 0.
  [in] | queue | Queue to execute in.
