View > Show Across > Thread

Displays the value of a variable in all threads in the process. When debugging a threaded program, seeing the value of a variable in all threads at the same time can be extremely useful. You can only turn on thread lamination if the process has more than one non-manager thread, and the variable being displayed depends on the stack or registers. (A static or global variable will have the same value in all threads, so there is no point seeing it use a view across command.)

When matching stack frames to construct a “view across” display, TotalView considers calls from different sites in the same function to be different.
