Krishna,
When you log in to the remote system, use ssh -X or ssh -Y which will
export the xterm back thru the ssh connection.

Hi,
I have been tracing the interactions between the PERUSE
and MPI library,on one machine. I have been using gdb along with xterm
to have two windows open at the same time as I step through the code.
I wish to get a better glimpse of the working of the point to point
calls, by launching the job on two machines and by tracing the flow in
a similar manner. This is where I stand as of now :
mpirun --prefix /usr/local -hostfile machines -np 2 xterm -e gdb
peruse_ex1
xterm Xt error: Can't open display:
xterm: DISPLAY is not set
I tried using the display option for xterm and setting
the value as 0.0, that was not of much help.
If someone can guide me as to where the DISPLAY
parameter has to be set to allow the remote machine to open the xterm
window, it will be of great help.
Thanks,
Krishna
