Processes/Ranks Tab

Displays a grid containing all of the processes in the current control group. If you are debugging an MPI program, TotalView displays ranks instead of processes.

 

Figure 33: Processes Tab

The block’s color represents the state, as follows:

Color	Meaning
Blue	Stopped; usually due to another process or thread hitting a breakpoint
Orange	At breakpoint.
Green	All threads in the process are running or can run.
Red	The Error state usually indicates that your program received a fatal signal from the operating system. Signals such as SIGSEGV, SIGBUS, and SIGFPE can indicate an error in your program.
Gray	The process has not begun running.

Diving (clicking) on a block switches the context within the Process Window so that the Process is contained within the Process Window. If the process contains more than one thread, TotalView switches to the first worker thread. That is, it does not switch context to a manager thread.

If you select a group within the scope pulldown, which at the upper-left corner of the Process Window, TotalView dims blocks representing processes that are not within the group.
