CECAM VIRTUAL 2021

Plan for the CECAM VIRTUAL 2021 school tutorials. https://www.cecam.org/workshop-details/1081

Setting up Yambo

Setting up the Yambo Quantum Machine

The tutorials will be run on a dedicated Quantum Machine. This is run by installing it as Virtual Machine with the VirtualBox program.

• VirtualBox is installed on your PC. To find it open a terminal and

>which virtualbox
/usr/bin/virtualbox

• The Yambo Quantum Machine image (.ova file) is already in the /scratch

>cd /scratch
>/scratch$ ls
(...) YAMBO_Quantum_Mobile.ova

Now follow exactly the instructions to

• Install the Yambo Quantum Machine
• Start the Yambo Quantum Machine
• Update and install the Tutorials
