OMP mulithreaded executable with single thread seems noticeably slower than non-OMP thread executable. This is probably due to many $omp parallel-do sections in the code. I have combined most of parallel-do sections, but there still a few remain, i.e. in BOCACL and QEq.

by fusing omp parallel-do clauses has improved the single thread performance of the multithreaded code. I would say that this issue has been more less resolved, or at least know what to do.
