Remote X11 display from compute node

Alternately, you can use VNC which can be faster for slow connections: Setting_Up_VNC_Session

Example program: IGV

Install/Start X on Desktop

ssh conection with X11 support

ssh -X to cheaha

Connect to cheaha head node with X-forwarding:

 ssh -X cheaha.uabgrid.uab.edu
 # check that "echo $DISPLAY" shows you something
 # check that "xterm" works

Windows/ PuTTY ssh

Check that Connection > SSH > X11 has a checkmark next to "Enable X11 forwarding"

Get a compute node

  • allocate compute node with qlogin, with appropriate time/memory
    • WARNING: if you run IGV on the cluster head-node, you will bring on the wrath of the cluster admins!!
 # 4 hours, 6G RAM
 qlogin -N IGV_6g -l h_rt=0:04:00,vf=6G
 # check that "echo $DISPLAY" shows you something
 # check that "xterm" works

Launch app

IGV

 # WARNING: run only on compute nodes, NEVER on head-node
 /share/apps/ngs-ccts/IGV/igv.sh
 # or
 /share/apps/ngs-ccts/IGV/igv6g  # doesn't seem to give 6G ram...
