When you are running a multi-threaded program, you see lots of threads. Some were created by your program; others weren't.

[/url]For example, your program will not have created the threads having a negative thread ID (TID). What's going on is that the operating system is creating additional threads to do some work for you. These threads are called manager threads.[br]
[/url]In most cases, TotalView can identify these manager threads and assigns a negative TID value to them so you know they aren't part of your program, and, in almost all cases, you can ignore them. If you don't want TotalView to show them to you, select the View > Display Manager Threads toggle command.[br]
