The OpenMP API includes two tool interfaces, OMPT and OMPD, to enable development of high-quality, portable, tools that support monitoring, performance, or correctness analysis and debugging of OpenMP programs developed using any implementation of the OpenMP API.
An implementation of the OpenMP API may differ from the abstract execution model described by its specification. The ability of tools that use the OMPT or OMPD interfaces to observe such differences does not constrain implementations of the OpenMP API in any way.
