DPCT1071

Message

The placement of the FFT computational function could not be deduced, so it is assumed out-of-place. You may need to adjust the code.

Detailed Help

If the last two arguments in the original API call are literally identical (ignoring C-Style type casts) and both the plan call and the execution call are in the same function, the Intel® DPC++ Compatibility Tool generates in-place placement. Otherwise, it assumes out-of-place placement.
The difference of in-place and out-of-place may affect the value of
FWD_DISTANCE
,
BWD_DISTANCE
,
INPUT_STRIDES
, and
OUTPUT_STRIDES
.

Suggestions to Fix

If the placement is incorrect, you may need to manually add the necessary
set_value()
statements before the call to
commit()
.
