PETSC debugger

[Ryan Yan]

Thank you very much, Barry.

After I use the vyan2000-linux:0.0, I got errors without any gdb window.

vyan2000 at 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
[0]PETSC ERROR: PETSC: Attaching gdb to ./rpisolve of pid 26518 on display
vyan2000-linux:0.0 on machine vyan2000-linux
[1]PETSC ERROR: PETSC: Attaching gdb to ./rpisolve of pid 26519 on display
vyan2000-linux:0.0 on machine vyan2000-linux
xterm Xt error: Can't open display: vyan2000-linux:0.0
xterm Xt error: Can't open display: vyan2000-linux:0.0

Then
I changed back,
vyan2000 at 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

Same as before, error messages with only a single gdb window, (and the
window shows up at different place at different instances).
