Connections to compute nodes
When a job is running on a compute node, the owner of the job can access the
ssh from a development node. This will connect your terminal to the
shell on the compute node where the job is running.
If your job is running on
amr-070 the command would be
ssh amr-070. Once on the compute node
you can inspect individual CPU and memory usage with
Connecting from your local machine
If you have SSH Tunneling set up, we can extend the ProxyJump framework to connect to compute nodes.
To do this, add the following lines to your
1 2 3
The three-letter names correspond to the kinds of nodes available from each cluster.
Notice that we are using the development node
intel18 to connect to the compute nodes, rather than the gateway.
We can then run a command such as
ssh amr-070 from our local terminal (assuming we have a job running on that node). This will connect us directly to that node.
Using OnDemand you can access the compute node
that your job is running on in the same way by opening a development node from
the Development Nodes menu and then using the
ssh command as described above.
You can identify the node for interactive sessions from the My Interactive
Sessions tab. It is located after the word "Host". Do not include the
characters in your
ssh command. The image below shows a job running on the
