TotalView Users Guide - CI Wiki

Viewing Process and Thread States
If the thread ID that TotalView assigns is the same as the operating system thread ID
your, TotalView only displays ID. If you are debugging an MPI program, TotalView displays
the thread’s rank number.
Seeing Attached Process States
Seeing Unattached Process States
TotalView uses the letters shown in the following table to indicate process
and thread state. (These letters are in the Status column in the Root Window,
as the figure in the previous section shows.)
State Code State Description
blank Exited or never created
B At breakpoint
E Error reason
H Held
K In kernel
L (cell only) Loose—Indicates slave SPU threads that are not held
and not currently bound to PPU threads
M Mixed
R Running
T Stopped reason
W At watchpoint
The error state usually indicates that your program received a fatal signal,
such as SIGSEGV, SIGBUS, or SIGFPE, from the operating system. See “Handling
Signals” on page 69 for information on controlling how TotalView handles
signals that your program receives.
CLI: The CLI prints out a word indicating the state; for example, “breakpoint.”
Seeing Unattached Process States
Seeing Attached Process States
TotalView derives the state information for a process displayed in the File >
New Program dialog box’s Attach to an existing process state from the
operating system. The state characters TotalView uses to summarize the
state of an unattached process do not necessarily match those used by the
operating system. The following table describes the state indicators that
TotalView displays:
State Code State Description
I Idle
R Running
S Sleeping
T Stopped
Z Zombie (no apparent owner)
