Attaching to an SGI MPI Job

TotalView : TotalView User Guide : PART III Parallel Debugging : Setting Up Parallel Sessions : MPI Program Setup : SGI MPI Applications : Attaching to an SGI MPI Job

To attach to a running SGI MPI program, attach to the SGI MPI mpirun process that started the program. The procedure for attaching to an mpirun process is the same as that for attaching to any other process.

After you attach to the mpirun process, TotalView asks if you also want to attach to slave MPICH processes. If you do, press Return or choose Yes. If you do not, choose No.

If you choose Yes, TotalView starts the server processes and acquires all MPICH processes.

Classic UI Only: As an alternative, use the Group > Attach Subset command to predefine what TotalView should do.
