Reorganize the section on debuggers

[gkaf89]

For parallel application debugging, we support tmpi. We can provide a few examples. Assuming we provide a tmpi that requires a system tmux and depends on the gompi toolchain and GDB:

• Start application with: tmpi 4 gdb --command=command.gdb --args ./airport --nplanes=2 --synch=4 --nkp=4
• You can use commad.gdb to define break points:

  break tw_kp_onpe
  break tw-setup.c:187
  break tw-setup.c:265
  break tw-setup.c:280
  break tw-setup.c:298
  break airport.c:182
  # debug
  

• Exit with the tmux command kill-window.

Type info variables to list "All global and static variable names" (huge list.

Type info locals to list "Local variables of current stack frame" (names and values), including static variables in that function.

Type info args to list "Arguments of the current stack frame" (names and values).
