Using TotalView with your Cray XT System

As part of launching an application on a compute node, TotalView launches a server program on your login node using ssh. As with any ssh session, authentication is required. We recommend that you enable ssh without a pass phrase.

TotalView typically runs interactively. If your site has not designated any compute nodes for interactive processing, use the PBS Pro qsub -I interactive mode. This mode is described in the Cray XT3 Programming Environment User’s Guide.

If TotalView is installed on your system, use the following command to load it into your user environment:

module load xt-totalview

You can now use the following command to start the CLI:

totalviewcli yod [-a argument_list] application_name

Here’s the command that starts the GUI:

totalviewcli yod [-a argument_list] application_name

The following example shows how you can debug a program named a.out:

% qsub -I -l size=4

qsub: waiting for job 14448.nid00003 to start

qsub: job 14448.nid00003 ready
