19 OMPT Interface

This chapter describes OMPT, which is an interface for ﬁrst-party tools. First-party tools are linked or loaded directly into the OpenMP program. OMPT deﬁnes mechanisms to initialize a tool, to examine OpenMP state associated with an OpenMP thread, to interpret the call stack of an OpenMP thread, to receive notiﬁcation about OpenMP events, to trace activity on OpenMP target devices, to assess implementation-dependent details of an OpenMP implementation (such as supported states and mutual exclusion implementations), and to control a tool from an OpenMP application.
