Hi Unfortunately this does not solve my problem. While i can do ssh -Y squid_0 xterm and this will open an xterm on m,y machiine (chefli), i run into problems with the -xterm option of openmpi:
jody@chefli ~/share/neander $ mpirun -np 4 -mca plm_rsh_agent "ssh -Y" -host squid_0 --xterm 1 hostname squid_0 [squid_0:28046] [[35219,0],1]->[[35219,0],0] mca_oob_tcp_msg_send_handler: writev failed: Bad file descriptor (9) [sd = 8] [squid_0:28046] [[35219,0],1] routed:binomial: Connection to lifeline [[35219,0],0] lost [squid_0:28046] [[35219,0],1]->[[35219,0],0] mca_oob_tcp_msg_send_handler: writev failed: Bad file descriptor (9) [sd = 8] [squid_0:28046] [[35219,0],1] routed:binomial: Connection to lifeline [[35219,0],0] lost /usr/bin/xterm Xt error: Can't open display: localhost:11.0 By the way when i look at the DISPLAY variable in the xterm window opened via squid_0, i also have the display variable "localhost:11.0" Actually, the difference with using the "-mca plm_rsh_agent" is that the lines wiht the warnings about "xauth" and "untrusted X" do not appear: jody@chefli ~/share/neander $ mpirun -np 4 -host squid_0 -xterm 1 hostname Warning: untrusted X11 forwarding setup failed: xauth key data not generated Warning: No xauth data; using fake authentication data for X11 forwarding. squid_0 [squid_0:28337] [[34926,0],1]->[[34926,0],0] mca_oob_tcp_msg_send_handler: writev failed: Bad file descriptor (9) [sd = 8] [squid_0:28337] [[34926,0],1] routed:binomial: Connection to lifeline [[34926,0],0] lost [squid_0:28337] [[34926,0],1]->[[34926,0],0] mca_oob_tcp_msg_send_handler: writev failed: Bad file descriptor (9) [sd = 8] [squid_0:28337] [[34926,0],1] routed:binomial: Connection to lifeline [[34926,0],0] lost /usr/bin/xterm Xt error: Can't open display: localhost:11.0 I have doubts that the "-Y" is passed correctly: jody@triops ~/share/neander $ mpirun -np -mca plm_rsh_agent "ssh -Y" -host squid_0 xterm xterm Xt error: Can't open display: xterm: DISPLAY is not set xterm Xt error: Can't open display: xterm: DISPLAY is not set ---> as a matter of fact i noticed that the xterm option doesn't work locally: mpirun -np 4 -xterm 1 /usr/bin/printenv prints verything onto the console. Do you have any other suggestions i could try?
