Assigning IDs to Processes and Threads
An application may have multi-processes and multithreads. Processes fall into two categories, depending on when they are created:
Initial processA pre-existing process from the normal run-time environment (that is, created outside TotalView), or one that was created as TotalView loaded the program.
Spawned processA new process created by a process executing under CLI control.
TotalView assigns an integer value to each individual process and thread under its control. This process/thread identifier can be the system identifier associated with the process or thread or an arbitrary value created by the CLI.
Process numbers are unique over the lifetime of a debugging session; in contrast, thread numbers are unique only while the process exists.
Process/thread notation identifies the component that a command targets. For example, if your program has two processes and each has two threads, four threads exist:
Thread 1 of process 1
Thread 2 of process 1
Thread 1 of process 2
Thread 2 of process 2
Identify the four threads as follows:
1.1—Thread 1 of process 1
1.2—Thread 2 of process 1
2.1—Thread 1 of process 2
2.2—Thread 2 of process 2
