Remote display from compute node
Example program: IGV
Install/Start X on Desktop
- Windows: X-Win32 from UAB IT
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...
