Types of IDs
Multithreaded, multi-process, and distributed programs contain a variety of IDs. The following types are used in the CLI and the UI:
System PID
The process ID, generally called the PID.
System TID
The ID of the system kernel or user thread. On some systems (for example, AIX), the TIDs have no obvious meaning. On other systems, they start at 1 and are incremented by 1 for each thread.
TotalViewthread ID
Usually identical to the system TID. On some systems (such as AIX) where the threads have no obvious meaning, TotalView uses its own IDs.
pthread ID
The ID assigned by the Posix pthreads package. If this differs from the system TID, the TID is a pointer value that points to the pthread ID.
Debugger PID
An ID created by TotalView to identify processes. It is a sequentially numbered value beginning at 1 that is incremented for each new process. If the target process is killed and restarted (that is, you use the dkill and drun commands), the TotalView PID does not change. The system PID changes, however, since the operating system has created a new target process.
