Development / Prototyping

Although you should always run analyses via the job scheduler, there are times when you may need to develop parts of it interactively at the command-line prompt. For instance, you may need to install some software, a few R packages, or run some quick tests on your new pipeline. Wynton provides development nodes dedicated for such short-term usages and that are configured similarly to the compute nodes.

Please do not run your real-world analysis on the development nodes. Instead run it as a job via the scheduler - this will assert that your analysis runs as fast as possible and with all the resources it needs. For further instruction, see the getting-started page Submit Job to Cluster.

Any shell session that has been idle for more than eight hours will timeout and exit automatically.

Instructions

To access one of the development node, say, dev3,

make sure you are logged in to the cluster, and
type ssh dev3 and press ENTER.

Example

From one of the login nodes, do:

[alice@wynlog2 ~]$ ssh dev3
alice1@dev3:s password: XXXXXXXXXXXXXXXXXXX
[alice@dev3 ~]$ 

As from the login nodes, it is possible to submit jobs also from the development nodes.
