Abstract: The purpose of this benchmark is to propose several optimization techniques and to test their existence in current OpenMP compilers. Examples are the removal of redundant synchronization constructs, effective constructs for alternative code and orphaned directives. The effectiveness of the compiler generated code is measured by comparing different OpenMP constructs and compilers. If possible, we also compare with the hand coded "equivalent" solution. Six out of seven proposed optimization techniques are already implemented in different compilers. However, most compilers implement only one or two of them.
