Arguments

Type IntentOptional Attributes Name
type(cufftReshapeHandle), value :: reshapeHandle

The reshape handle.
type(c_ptr), value :: dataOut

A symmetric-heap pointer to the output data. This memory should be NVSHMEM allocated and identical on all processes.
type(c_ptr), value :: dataIn

A symmetric-heap pointer to the input data. This memory should be NVSHMEM allocated and identical on all processes.
type(c_ptr), value :: workSpace

A symmetric-heap pointer to the workspace data. This memory should be NVSHMEM allocated and identical on all processes.
type(dtfft_stream_t), value :: stream

The CUDA stream in which to run the reshape operation.

Return Value integer(kind=c_int)

The enumerated type cufftResult defines API call result codes.
