Hi all, Below is a first draft of a mission statement for the tools WG that we were asked to provide. I would like to discuss this with the whole group at tomorrow's WG meeting. Please feel free to also comment via email if you can't make it to the meeting or if have any urgent comments (seems the MPI Forum seems to be reviewing some of these already). Thanks, Martin The goal of this working group is define interfaces that can be used by both performance and correctness tools to gain information about internals of the MPI library, interactions between an application and the MPI library, as well as the system environment an MPI application runs in. This is intended as an extension to the existing and widely used PMPI interface. These efforts will help in providing reliable and portable interfaces for MPI tools with new functionality currently not covered by the MPI standard. In particular, this WG is aiming at the standardization of the following interfaces: - A scalable version of a process acquisition interface to identify and locate all processes which are part of an MPI job. - An interface to look for and locate tool DLLs. - An interface to inspect message queues. - An interface to understand progress in collective communication. - An interface to query additional semantic information for opaque MPI handles. - A performance information interface that allows MPI implementations to export additional low level performance information including, but not limited to, the operating state of the MPI library. _______________________________________________________________________ Martin Schulz, [email protected], http://people.llnl.gov/schulzm CASC @ Lawrence Livermore National Laboratory, Livermore, USA
