Those waw dependences seem to be correct. Should even the previous analysis
only mark the j-loop as parallel?
The previous and the current analysis mark the j-loop as
nonparallelizable. (Possibly, I don't fully understand the question.
Could you please reformulate it?)
I would expect the to mark the i loop as non-parallel, but the j-loop
as parallel. What is the partial schedule, the set of dependences and
the dimension you check for both the i and the j loop?
Cheers,
