allocate1DArrayDevice()

float* allocate1DArrayDevice

(

size_t

n

)

Allocate a 1D array.

Parameters

n	The size of the array to allocate.

Returns

The allocated array.

copy1DArrayDevice()

float* copy1DArrayDevice	(	size_t	n,
		float *	old
	)

Copy the provided 1D array to a new location.

As opposed to copy1DFromDeviceToDevice(), this returns the new location, rather than expecting it as an argument.

Parameters

n	The size of the array to copy.
old	The array to copy.

Returns

The new array.

copy1DFromDeviceToDevice()

void copy1DFromDeviceToDevice	(	float *	oldLoc,
		float *	newLoc,
		size_t	n
	)

Copy a 1D array within device memory.

Parameters

oldLoc	The old location of the array.
newLoc	The new location of the array.
n	The size of the array.

copy1DFromDeviceToHost()

void copy1DFromDeviceToHost	(	float *	device,
		float *	host,
		size_t	n
	)

Copy a 1D array from device memory to host memory.

Parameters

device	The location of the device array.
host	The host location where the array should be copied.
n	The size of the array.

copy1DFromHostToDevice()

void copy1DFromHostToDevice	(	float *	host,
		float *	device,
		size_t	n
	)

Copy a 1D array from host memory to device memory.

Parameters

host	The location of the host array.
device	The device location where the array should be copied.
n	The size of the array.

copy2DFromDeviceToHost()

void copy2DFromDeviceToHost	(	float *	device,
		float **	host,
		size_t	n,
		size_t	m
	)

Copy a 2D array from device memory to host memory.

Parameters

device	The location of the device array.
host	The host location where the array should be copied.
n	The number of rows of the array.
m	The number of columns of the array.

copy2DFromHostToDevice()

void copy2DFromHostToDevice	(	float **	host,
		float *	device,
		size_t	n,
		size_t	m
	)

Copy a 2D array from host memory to device memory.

Parameters

host	The location of the host array.
device	The device location where the array should be copied.
n	The number of rows of the array.
m	The number of columns of the array.

free1DArrayDevice()

void free1DArrayDevice

(

float *

device

)

Free a 1D array from device memory.

Parameters

device

The array to free.
