6.2.1.4 Using TotalView with LSF-HPC
HP recommends the use of xterm when debugging an application with LSF-HPC. You also need to allocate
the nodes you will need.
You may need to verify the full path name of the xterm and mpirun commands:
First run a bsub command to allocate the nodes you will need and to launch an xterm window:
$ bsub -nx -ext "SLURM[nodes=x]" \
-Is /usr/bin/xterm
Enter an mpirun -tv command in the xterm window to start TotalView on the application you want
to debug:
$ mpirun -tv -srun application
6.2.1.5 Setting TotalView Preferences
You should set TotalView preferences the first time you invoke it. For example, you need to tell TotalView
how to launch TotalView processes on all the cores.
The TotalView preferences are maintained in a preferences file named .totalview/preferences in
your home directory, so you only need to set these preferences once.
Follow these steps to set the TotalView preferences:
1. Invoke the TotalView debugger:
$ totalview
TotalView's main control window (called the TotalView Root Window) appears.
2. Select Preferences from the File pull-down menu.
A Preferences window opens.
3. Select (that is, click on) the Launch Strings tab in the Preferences window.
4. Ensure that the Enable single debug server launch button is selected in the Launch Strings
tab.
5. In the Launch Strings table, in the area immediately to the right of Command:, verify that the
default command launch string shown is as follows:
%C %R -n "%B/tvdsvr -working_directory %D -callback %L -set_pw %P
-verbosity %V %F"
You may be able to obtain this setting by selecting the Defaults button; otherwise, you need to enter
this command launch string.
6. Select the Bulk Launch tab in the Preferences window.
Make sure that Enable debug server bulk launch is not selected.
7. Select the OK button at the bottom-left of the Preferences window to save these changes.
8. Exit TotalView by selecting Exit from the File pull-down menu.
The TotalView launch preferences are configured and saved. You can change this configuration at any
time.
6.2.1.6 Debugging an Application
This section describes how to use TotalView to debug an application.
1. Compile the application to be debugged. For example:
$ mpicc -g -o Psimple simple.c -lm
