RASESMA 2023 Nairobi

RASESMA flyer

Setting up Yambo, QE and the tutorials

To be able to follow the school you need (i) a running version of the yambo code, and (ii) the files and databases needed to run the tutorials.

You have several options to prepare all needed to run the tutorials.

Virtual Machine(s)

The easiest way is to access to a virtual machine which contains both (i) yambo and (ii) the tutorials.

You can do it in two alternative ways:

• Virtual machine via ICTP cloud (strongly suggested mode, works through internet connection inside a browser)
• Install the yambo virtual machine on your laptop / desktop (requires Oracle virtual box. Pre-download of the Virtual machine. No internet connection needed)

User installation

You can also setup the yambo code on your on laptop / desktop using different methods.

As far as the Yambo source is concerned you can:

• Install Yambo via Docker
• Download and install yambo on your laptop / desktop (requires a linux machine).
• Install yambo on your laptop/desktop/cluster via Spack.

Tutorials, instead, can be installed in two ways:

• Download the tutorial files following the instructions here
• Here the instruction to install Yambopy via conda

Sunday 19 Feb

For who will be already in Nairobi we will have a get together & Yambo installation session at the YMCA Central starting. Time will be decided on the basis of who will participate.
