Landing pad systems function as the gateway to access CCI resources.

NOTE! The landing pad systems are not to be used for compute intensive tasks.

Compute intensive tasks running on landing pads may be stopped by staff without warning. Please submit a serial job to one of the cluster queues.

If you require an interactive session for any reason, consider launching an interactive job through the scheduler requesting a graphical terminal instead:

salloc xterm -e 'ssh -X `srun hostname`'


The following landing pads are available for two-factor SSH connections:

These hosts share a common SSH public key fingerprint:

Data Movement

Use your favorite SCP or Rsync client to transfer data to the landing pad systems.

Connections to external systems from the landing pads (or any other system) are not allowed, except specific connections through the proxy.

Data transfers generally have to be initiated internally, whether transferring data to or from CCI.

TIP: All landing pads have access a common file system shared across all clusters.

Connecting to Other Systems

To access compute systems for job submission or compilation, you will need to SSH from the landing pad to the appropriate front-end node "FEN".

To access a system scheduled for you on the Landing Pads via SSH to debug or otherwise interact with your job you can use the hostname(s) indicated with the "squeue" command.
