Executes kernel on stream

Type Bound

kernel_device

Arguments

Type IntentOptional Attributes Name
class(kernel_device), intent(inout) :: self

Device kernel class
type(c_ptr), intent(in) :: in

Source buffer, can be device or host pointer
type(c_ptr), intent(in) :: out

Target buffer, can be device or host pointer
type(dtfft_stream_t), intent(in) :: stream

Stream to execute on
logical, intent(in) :: sync

Sync stream after kernel execution, unused here
integer(kind=int32), intent(in), optional :: neighbor

Source rank for pipelined unpacking
