Detailed Description

Macro Definition Documentation

magma_getvector	(		n,
			elemSize,
			dx_src,
			incx,
			hy_dst,
			incy,
			queue
	)

Copy vector dx_src on GPU device to hy_dst on CPU host.

Elements may be arbitrary size. Type-safe versions set elemSize appropriately.

This version synchronizes the queue after the transfer. See magma_getvector_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]	hy_dst	Destination array of dimension (1 + (n-1))*incy, on CPU host.
[in]	incy	Increment between elements of dy_dst. incy > 0.
[in]	queue	Queue to execute in.

magma_getvector_async	(		n,
			elemSize,
			dx_src,
			incx,
			hy_dst,
			incy,
			queue
	)

Copy vector dx_src on GPU device to hy_dst on CPU host.

Elements may be arbitrary size. Type-safe versions set elemSize appropriately.

This version is asynchronous: it may return before the transfer finishes, if hy_dst is pinned CPU memory. See magma_getvector() 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]	hy_dst	Destination array of dimension (1 + (n-1))*incy, on CPU host.
[in]	incy	Increment between elements of dy_dst. incy > 0.
[in]	queue	Queue to execute in.
