Viewing OpenMP* Information

The debugger provides information on OpenMP* locks, teams and threads when debugging an OpenMP* application.

To enable OpenMP* support, make sure the debugger has access to the shared library libomp_db.so, which by default is in the lib directory in your compiler installation.

The debugger automatically enables OpenMP* support when it detects that the debuggee is an OpenMP program. To switch off OpenMP* support, use the following command:

(idb) set $threadlevel="native"

To switch it back on, use the following command:

(idb) set $threadlevel="openmp"

The debugger enables you to view the following information about an OpenMP* application:
