Setting Action Points

This chapter explains how to use action points. TotalView has four kinds of action points:

A breakpoint stops execution of processes and threads that reach it.

A barrier point synchronizes a set of threads or processes at a location.

An eval point causes a code fragment to execute when it is reached.

A watchpoint lets you monitor a location in memory and stop execution when it changes.
