MPI 2 Processes for Scalable Parallel Debugging

Abstract:
This paper proposes an interface that will allow MPI 2
dynamic programs, those using MPI SPAWN, CONNECT/ACCEPT or JOIN, to
provide information to parallel debuggers such as TotalView about the
set of processes that constitute an individual application. The
TotalView parallel debugger currently obtains information about the
identify the processes directly from the MPI library using a widely
accepted proctable interface. The existing interface does not support
MPI 2 dynamic operations. The proposed interface supports MPI 2
dynamic operations, subset debugging, and helps the parallel debugger
assign meaningful names to processes.
