Detailed Description

Macro Definition Documentation

magma_copymatrix	(		m,
			n,
			elemSize,
			dA_src,
			ldda,
			dB_dst,
			lddb,
			queue
	)

Copy all or part of matrix dA_src on GPU device to dB_dst on GPU device.

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

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

Parameters

[in]	m	Number of rows of matrix A. m >= 0.
[in]	n	Number of columns of matrix A. n >= 0.
[in]	elemSize	Size of each element, e.g., sizeof(double).
[in]	dA_src	Source array of dimension (ldda,n).
[in]	ldda	Leading dimension of matrix A. ldda >= m.
[out]	dB_dst	Destination array of dimension (lddb,n), on GPU device.
[in]	lddb	Leading dimension of matrix B. lddb >= m.
[in]	queue	Queue to execute in.

magma_copymatrix_async	(		m,
			n,
			elemSize,
			dA_src,
			ldda,
			dB_dst,
			lddb,
			queue
	)

Copy all or part of matrix dA_src on GPU device to dB_dst on GPU device.

Elements may be arbitrary size. Type-safe versions set elemSize appropriately. With CUDA unified addressing, dA and dB 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]	m	Number of rows of matrix A. m >= 0.
[in]	n	Number of columns of matrix A. n >= 0.
[in]	elemSize	Size of each element, e.g., sizeof(double).
[in]	dA_src	Source array of dimension (ldda,n), on GPU device.
[in]	ldda	Leading dimension of matrix A. ldda >= m.
[out]	dB_dst	Destination array of dimension (lddb,n), on GPU device.
[in]	lddb	Leading dimension of matrix B. lddb >= m.
[in]	queue	Queue to execute in.
