for the weekend 23-25 March, Pluto HPC is switching off, due to the cooling failure in the HPC comms room to prevent hardware damage.

module load cuda/last will load ver. 9.0 of CUDA Toolkit paths. Nvidia drivers are also updated to CUDA-9 compatible (384.81) on all K80 (zeus[400-409) nodes)

SSH Tunnel to the HPC’s compute node from Uni network

For more recent Recommended approach see: http://zeus.coventry.ac.uk/wordpress/?p=1119
If you need to launch GUI application on the actual compute node the job was assigned to by slurm, you can do VNC-session through ssh-tunnel (tunneling from outside to the node via login node).
You can connect “directly” to one of the reserved nodes (node assigned by slurm to your job) from university network (or from outside via VPN) using ssh tunnel. E.g. on your local machine issue the command (we presume SSH is installed on your PC, if not, you can use cygwin from w:\Students\Shared\EC\STUDENT\HPC\cygwin\)
ssh -L 5901:zeus15:5901 username@zeus4.coventry.ac.uk
This will connect the port 5901 (i.e. VNC-server session :1 running on zeus15) to the port 5901 (you can hook it to any other if 5901 is already taken on your PC) of your local machine via login node zeus4. Obviously replace “username” by your HPC user name. Then, to connect to VNC session running on zeus15:1, just connect your vncviewer to localhost:1. If you need to forward any other non-privileged port from compute node to your local PC, just change the port numbers in the command above.
vncviewer localhost:1
