### log in to Rocket ON CAMPUS
- host: rocket.hpc.ncl.ac.uk
- username: YOUR username like c1234567

#### Can't access RDW?
* `kinit`
* `klist`
* log a ticket with NUIT

#### Need a new HPC project? Log a ticket:
Direct Link: [HPC - New Project / Service Catalogue / NU Service](https://nuservice.ncl.ac.uk/HEAT/Modules/SelfService/#serviceCatalog/request/BAB45A73C3C342F6A305D4D38A46FC88)

You will need:
* Name of research project or research area:

* Name of a secondary contact:
* List of the software which will be used (e.g. Python):
* Type of processing or computation which will be undertaken (e.g. CFD, sequencing, etc):

## Connecting from off-campus
We have to use unix.ncl.ac.uk as a 'jump host' _don't do this if you are ON campus - it will make things very slow_. To register for this service please complete the [registration form](https://forms.microsoft.com/e/uUir420SEX). The new Unix account will usually be ready for use the next day.
Before connecting, you need to log into the [NUIT Application Access Portal](https://ama.ncl.ac.uk/)

## Using Anaconda?
Anaconda won't be available on Comet, but [conda-forge](https://conda-forge.org/) will be available.

## Interesting Questions

Q: The `module avail` command doesn't run via `srun`.

A: The `module` command expects an interactive terminal (like your SSH session), you don't get one by default with the `srun` command. We can force one to be assigned with the `--pty` option, try:

`srun --pty --partition=short /bin/bash -c "module avail"`
