Filtering Array Data Overview

Totalview® for HPC User Guide : PART II Debugging Tools and Tasks : Chapter 10 Examining Arrays : Examining and Analyzing Arrays : Filtering Array Data Overview

You can restrict what TotalView displays in a Variable Window by adding a filter to the window. You can filter arrays of type character, integer, or floating point. Your filtering options are:

• Arithmetic comparison to a constant value

• Equal or not equal comparison to IEEE NaNs, Infs, and Denorms

• Within a range of values, inclusive or exclusive

• General expressions

When an element of an array matches the filter expression, TotalView includes the element in the Variable Window display.

The following topics describe filtering options:

• "Filtering Array Data"

• "Filtering by Comparison"

• "Filtering for IEEE Values"

• "Filtering a Range of Values"

• "Creating Array Filter Expressions"

• "Using Filter Comparisons"
