OVERVIEW

This page describes the differences between JADE and the older CentOS 7 cluster.

- JADE does not support graphical logins such as XRDP or X2go; this is by design, to ensure that as much of the available resources are usable for other purposes. This can cause issues when making graphical plots in R; please see R-cbrg(7) for further details.

- The JADE login nodes are provided in order to allow file managment, light development work and submission of jobs to the cluster and not for running code or pipelines. As such, all user logins have limited access to CPU and memory. See welcome(7) for more details and slurm-basics(7) to learn how to submit an interactive session and get access to more CPU and memory.

- Multiple Python-based packages have been moved into python-cbrg(7) , both to improve our ability to update them and to reduce duplication. Please check whether packages are part of python-cbrg(7) before opening a help request to have them installed.

- The Slurm scheduler is configured with multiple queues to enable a fairer share of the resources. See slurm-basics(7) for more details.

- Conda is not installed centrally and we are only able to offer the most basic support for Conda related issues. (Note that Conda is also not supported on CentOS, but was installed centrally for some time)

- JADE uses a modern version of Ubuntu Linux, and work started on JADE should not be moved back onto CentOS as it may not be fully backwards compatible

- JADE correctly differentiates between the Bash as Sh command shells, with the result that you must specify Bash directly in your shell scripts. Please ensure that you use #!/bin/bash , especially in Slurm scripts.

- JADE uses a different setup for the Bash initialisation scripts. If you find that your command line colours for directories are missing, you can fix this by resetting your configuration, but please note that once you've done this you should not attempt to use the old CentOS cluster again - if you do, it may not work correctly. To reset your configuration, please log into JADE and run the following commands (you will need to manually re-add any custom configuration afterwards):

$ cd ~
$ cp .bashrc .bashrc.backup
$ cp /etc/skel/.bashrc .
