cuMallComplex()

std::vector< cuFloatComplex * > MemUtils::cuMallComplex ( int &  n, int &  size  )

inline

Allocate memory for cuFloatComplex on GPU and return pointers.

Parameters

n	Number of pointers to allocate on GPU.
size	Number of elements to allocate.

Returns

out Vector containing GPU-allocated pointers.

cuMallComplexStack()

std::vector< cuFloatComplex * > MemUtils::cuMallComplexStack ( int &  n, int &  size  )

inline

Allocate memory for cuFloatComplex on local stack and return pointers.

Parameters

n	Number of pointers to allocate on GPU.
size	Number of elements to allocate.

Returns

out Vector containing stack-allocated pointers.

cuMallFloat()

std::vector< float * > MemUtils::cuMallFloat ( int &  n, int &  size  )

inline

Allocate memory for floats on GPU and return pointers.

Parameters

n	Number of pointers to allocate on GPU.
size	Number of elements to allocate.

Returns

out Vector containing GPU-allocated pointers.

cuMallFloatStack()

std::vector< float * > MemUtils::cuMallFloatStack ( int &  n, int &  size  )

inline

Allocate memory for floats on host stack and return pointers.

Parameters

n	Number of pointers to allocate on stack.
size	Number of elements to allocate.

Returns

out Vector containing stack-allocated pointers.

cuMemCpComplex()

void MemUtils::cuMemCpComplex ( std::vector< cuFloatComplex * >  vecFloat, std::vector< cuFloatComplex * >  vecData, int &  size, bool  H2D = true  )

inline

Copy local arrays of cuFloatComplex to allocated memory on GPU.

Parameters

vecFloat	Vector containing allocated pointers to arrays of floats.
vecData	Vector containing pointers to local arrays.
size	Number of elements to copy.
H2D	Direction of copy. If true (default), copy from host to device. If false, copy from device to host.

void MemUtils::cuMemCpFloat ( std::vector< float * >  vecFloat, std::vector< float * >  vecData, int &  size, bool  H2D = true  )

inline

Copy local arrays of floats to allocated memory on GPU.

Parameters

vecFloat	Vector containing allocated pointers to arrays of floats.
vecData	Vector containing pointers to local arrays.
size	Number of elements to copy.
H2D	Direction of copy. If true (default), copy from host to device. If false, copy from device to host.

deallocComplexHost()

void MemUtils::deallocComplexHost ( std::vector< cuFloatComplex * >  vecFloat )

inline

Deallocate local arrays of floats.

Parameters

vecFloat

Vector containing pointers to local arrays to deallocate.

deallocFloatHost()

void MemUtils::deallocFloatHost ( std::vector< float * >  vecFloat )

inline
