Implementation and Usage of the PERUSE-Interface in Open MPI
[chapter]
2006
Lecture Notes in Computer Science
This paper describes the implementation, usage and experience with the MPI performance revealing extension interface (Peruse) into the Open MPI implementation. While the PMPI-interface allows timing MPI-functions through wrappers, it can not provide MPI-internal information on MPI-states and lower-level network performance. We introduce the general design criteria of the interface implementation and analyze the overhead generated by this functionality. To support performance evaluation of
