Hi Barry, <br>I restarted x server many times(during turning off the option as ) -nolisten tcp as Berend. And I also checked very carefully each time the bottom margin of the window status panel. The gdb window did not function correctly on my Linux box. Thanks in advance for any suggestions<br>

Are you sure the other window isn't lurking away somewhere off (or nearly) off the screen?<br>
<br>
Maybe try shutting down the x server and restarting?<br><font color="#888888">

Thank you very much, Barry.<br>

After I use the vyan2000-linux:0.0, I got errors without any gdb window.<br>
<br>
vyan2000@vyan2000-linux:~/local/PPETSc/petsc-2.3.3-p15/src/ksp/ksp/examples/tutorials/ttt2$ mpirun -np 2 ./rpisolve -ksp_monitor_true_residual -start_in_debugger -display vyan2000-linux:0.0<br>

xterm Xt error: Can't open display: vyan2000-linux:0.0<br>
<br>
Then<br>
I changed back,<br>
vyan2000@vyan2000-linux:~/local/PPETSc/petsc-2.3.3-p15/src/ksp/ksp/examples/tutorials/ttt2$ mpirun -np 2 ./rpisolve -ksp_monitor_true_residual -start_in_debugger -display :0.0<br>
<br>
Same as before, error messages with only a single gdb window, (and the window shows up at different place at different instances).<br>

Try using -display vyan2000-linux:0.0<br>
<br>
Shouldn't make any difference but since it appears you are running everything on the same machine what you have given should work.<br>

Hi All,<br>
I am tring to use the PETSc runtime option -start_in_debugger.<br>
<br>
However, when I attach the debugger at run time to each process, there are error messages and I only get one gdb window(Am I suppose to get as many as the number of the processes?)<br>
<br>
vyan2000@vyan2000-linux:~/local/PPETSc/petsc-2.3.3-p15/src/ksp/ksp/examples/tutorials/ttt2$ mpirun -np 2 ./rpisolve -ksp_monitor_true_residual -start_in_debugger -display :0.0<br>
<br>
[1]PETSC ERROR: PETSC: Attaching gdb to ./rpisolve of pid 26307 on display :0.0 on machine vyan2000-linux<br>
[0]PETSC ERROR: PETSC: Attaching gdb to ./rpisolve of pid 26306 on display :0.0 on machine vyan2000-linux<br>
<br>
Then, only a *single* gdb window prompts out. When I run with 3 process, there are only *two* gdb windows.<br>
<br>
Thank you very much in advance,<br>
<br>
