Totalview® for HPC User Guide : PART II Debugging Tools and Tasks : Chapter 7 Stepping through and Executing your Program : Continuing with a Specific Signal
Continuing with a Specific Signal
Letting your program continue after sending it a signal is useful when your program contains a signal handler. To set this up:
1. Select the Process Window’s Thread > Continuation Signal command.
Figure 85 – Thread > Continuation Signal Dialog Box
2. Select the signal to be sent to the thread and then select OK.
The continuation signal is set for the thread contained in the current Process Window. If the operating system can deliver multi-threaded signals, you can set a separate continuation signal for each thread. If it can’t, this command clears continuation signals set for other threads in the process.
3. Continue execution of your program with commands such as Process > Go, Step, Next, or Detach.
TotalView continues the threads and sends the specified signals to your process.
NOTE >> To clear the continuation signal, select signal 0 from this dialog box.
You can change the way TotalView handles a signal by setting the TV::signal_handling_mode variable in a .tvdrc startup file. For more information, see Chapter 4 of the “TotalView for HPC Reference Guide.”
