Sorting by key with tuple key and customized comparison operator

Sorting an array by key is possible once an ordering is defined for the tuple key.
Defining an ordering is possible with CUDA Thrust by an overload of the “<” comparison operator.

Accordingly, sorting tuples with CUDA Thrust can be performed by a combination of thrust::sort_by_key, zip iterators and tuples.
Our GitHub web page contains an example on how this can be simply accomplished.
