Setting Breakpoints and Barriers
TotalView has several options for setting breakpoints, including:
• Source-level breakpoints
• Breakpoints that are shared among all processes in multi-process programs
• Assembler-level breakpoints 
You can also control whether TotalView stops all processes in the control group when a single member reaches a breakpoint.
