About OpenMP Platform Differences
In general, TotalView smooths out the differences that occur when you execute OpenMP platforms on different platforms. The following list discusses these differences:
• The OpenMP master thread has logical thread ID number 1. The OpenMP worker threads have a logical thread ID number greater than 1.
• Select or dive on the stack parent token line to view the original routine’s stack
frame in the OpenMP master thread.
• When you stop the OpenMP worker threads in a PARALLEL DO outlined routine, the stack backtrace shows the following call sequence:
— Outlined routine called from the special stack parent token line.
— The OpenMP runtime library called from.
— The original routine (containing the parallel region).
