Proposed Draft Technical Reports

• OMPT and OMPD: OpenMP Tools Application Programming Interfaces for Performance Analysis and Debugging - (PDF) To enable portable tools for performance analysis and debugging of OpenMP programs, we define an application programming interface (API) for tools that we propose for adoption as part of the OpenMP standard and supported by all OpenMP compliant implementations.
  There are two parts to the proposed interface:  OMPT - a first-party API for performance tools, and OMPD - a shared-library plugin for debuggers that enables a debugger to inspect and control execution of an OpenMP program. (May 2013)
