mpiexec -idb -n 2 <myprogram> error

[____1]

the program is compiled by intel fortran compiler 10.1 in linux IA64

program can run , but i can't use idb

when id input "mpiexec -idb -n 2 ./helloword" to my console,

it output : xterm Xt error: Can't open display:

does the idb need Xserver? i only use the console

i debug the program only in console,I doesn't have Xserver

use ssh -X ,the idb can startup
but ,
