Do you also have performance data to support your statement that
OpenMP is slowing things down in this case?
Please see the attached file. Apparently the case (4) is the fastest, that is, OMP palatalization shouldn't be used for these small section.
If I read the numbers correctly, then the original code is the fastest in all cases, sometimes by a factor of five.
