I don't think the "debugger" option to mpirun will work with gdb - I believe it 
is intended to work with parallel debuggers such as Totalview. Looking at the 
code, I certainly can't see how gdb would work correctly with it.

There is an mpirun option "-xterm" which will launch the xterm windows 
automatically for you, but that doesn't resolve your problem as it basically 
does what you are doing  manually.

It is unclear why you can't run gdb this way on a remote computer. Is something 
wrong with xterm? Do you not have an xterm client running on your remote 
computer?
