Visualizing Data Manually

Totalview® User Guide : PART II Debugging Tools and Tasks : Chapter 11 Visualizing Programs and Data : Array Visualizer : Visualizing Data Manually

Before you can visualize an array:

• Open a Variable Window the array.

• Stop program execution when the array’s values reflect what you want to visualize.

You can restrict the visualized data by editing the Slice field. (See “Displaying Array Slices”.) Limiting the amount of data increases the speed of the Visualizer.

After selecting the Variable Window Tools > Visualize command, the Visualizer creates its window.

NOTE >> As you step through your program, be aware that the data sent to the Visualizer is not automatically updated; explicitly update the display using Tools > Visualize.

TotalView can visualize variables across threads or processes. (See “Visualizing a “Show Across” Variable Window”.) In this case, the Visualizer uses the process or thread index as one dimension, meaning that you can visualize only scalar or vector information. If you do not want the process or thread index to be a dimension, do not use a Show Across command.
