====== Cylc (& Rose) ======

**Cylc** (https://cylc.github.io/cylc/) is a workflow management system developed at **NIWA** and the **UK MetOffice**.
It has good cycling capabilities and it provides a friendly graphical user interface client that needs to be installed in the **'suite host'**.
It can be configured to submit jobs to **'task hosts'** remotely using a HTTP channel, and the most common workload managers are suportted (PBS, LSF, GE, Slurm, etc.).
If communications from the task host to the suite host is not permitted, **polling** is allowed.

===== How to install Cylc =====

  * Cylc is deployed on **BSC-ES "bscearth200"** virtual machine, available for all Earth department users.
  * Cylc is deployed on **ECMWF "ecgate"** under /home/ms/gb/frmi/ account.

It is relatively easy to install following the official quick installation guide:

https://github.com/cylc/cylc/blob/master/INSTALL.md

Below I provide the steps I followed to deploy it on BSC-ES virtual machine. These steps could be used by BSC-operations to make the deploy available on Earth workstations via modules environment.
