Class CudaFFTPlanMany64

Creates a FFT plan configuration of dimension rank, with sizes specified in the array n. The batch input parameter tells CUFFT how many transforms to configure in parallel. With this function, batched plans of any dimension may be created.

Input parameters inembed, istride, and idist and output parameters onembed, ostride, and odist will allow setup of noncontiguous input data in a future version (Beta status in version 4.0). Note that for CUFFT 3.0, these parameters are ignored and the layout of batched data must be side‐by‐side and not interleaved.

Exec(CUdeviceptr)

Executes a CUFTT transorm as defined by the cufftType. This method does an in‐place transform.

This method is only valid for transform types where transorm direction is implicitly given by the type (i.e. not C2C and not Z2Z)

Declaration

public void Exec(CUdeviceptr iodata)

Parameters

Type	Name	Description
CUdeviceptr	iodata

Exec(CUdeviceptr, CUdeviceptr)

Executes a CUFTT transorm as defined by the cufftType. If idata and odata are the same, this method does an in‐place transform.

This method is only valid for transform types where transorm direction is implicitly given by the type (i.e. not C2C and not Z2Z)

Declaration

GetActualSize()

Once plan generation has been done, either with the original API or the extensible API, this call returns the actual size of the work area required to support the plan. Callers who choose to manage work area allocation within their application must use this call after plan generation, and after any cufftSet*() calls subsequent to plan generation, if those calls might alter the required work space size.

Declaration

public SizeT GetActualSize()

Returns

Type	Description
SizeT

| Improve this Doc View Source

GetSize()

This call gives a more accurate estimate of the work area size required for a plan than cufftEstimate1d(), given the specified parameters, and taking into account any plan settings that may have been made.

Declaration

public SizeT GetSize()

Returns

Type	Description
SizeT

SetAutoAllocation(Boolean)

SetAutoAllocation() indicates that the caller intends to allocate and manage work areas for plans that have been generated. CUFFT default behavior is to allocate the work area at plan generation time. If cufftSetAutoAllocation() has been called with autoAllocate set to "false" prior to one of the cufftMakePlan*() calls, CUFFT does not allocate the work area. This is the preferred sequence for callers wishing to manage work area allocation.

Declaration

public void SetAutoAllocation(bool autoAllocate)

Parameters

Type	Name	Description
System.Boolean	autoAllocate

SetCompatibilityMode(Compatibility)

configures the layout of CUFFT output in FFTW‐compatible modes. When FFTW compatibility is desired, it can be configured for padding only, for asymmetric complex inputs only, or to be fully compatible.

Declaration

public void SetCompatibilityMode(Compatibility mode)

Parameters

Type	Name	Description
Compatibility	mode

SetStream(CUstream)

Associates a CUDA stream with a CUFFT plan. All kernel launches made during plan execution are now done through the associated stream, enabling overlap with activity in other streams (for example, data copying). The association remains until the plan is destroyed or the stream is changed with another call to SetStream().

Declaration

public void SetStream(CUstream stream)

Parameters

Type	Name	Description
CUstream	stream

SetWorkArea(CUdeviceptr)

SetWorkArea() overrides the work area pointer associated with a plan. If the work area was auto-allocated, CUFFT frees the auto-allocated space. The cufftExecute*() calls assume that the work area pointer is valid and that it points to a contiguous region in device memory that does not overlap with any other work area. If this is not the case, results are indeterminate.

Declaration

public void SetWorkArea(CUdeviceptr workArea)

Parameters

Type	Name	Description
CUdeviceptr	workArea
