Using the Processes/Ranks Tab

The Processes tab, which is called a Ranks tab if you are running an MPI program, contains a grid. Each block in the grid represents one process. The color that TotalView uses to display a process indicates the process’s 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. Signals such as SIGSEGV, SIGBUS, and SIGFPE can indicate an error in your program.
Gray	The process has not begun running.

Figure 149 shows a tab with processes in three different states:

If you select a group by using the Process Window’s group selector pulldown (see “Using the Toolbar to Select a Target” for information), TotalView dims the blocks for processes not in the group, Figure 150.

CLI: dptsets

If you click on a block, the context within the Process Window changes to the first thread in that process.

CLI: dfocus

Clicking on the P+ and P– buttons in the tab bar also changes the process being displayed within the Process Window.
