=== Setting up the Yambo Container===
=== Setting up the Yambo Container===


An alternative to get the Yambo code is to install the Yambo container in your machine and this can be done in few steps:
- Install [[Yambo via Docker|Yambo via Docker]] on your laptop / desktop
 
* Install the docker platform (Linux or Mac). Follow the instruction  in the docker [https://docs.docker.com/engine/install/ website].
* Pull the Yambo container:
 
  sudo docker pull nicspalla/yambo-gcc_openmp_petsc:latest
 
sudo it is not necessary if your user is part of the group named docker (suggested on Linux!).
 
For Linux users:
 
  sudo groupadd docker
  sudo usermod -aG docker $USER
 
For Mac users:
 
  sudo dscl . create /Groups/docker
  sudo dseditgroup -o edit -a $USER -t user docker
 
Log out and log back in so that your group membership is re-evaluated.
 
* You are done. To run Yambo into the container:
 
docker run -ti --user $(id -u):$(id -g) \
    --mount type=bind,source="$(pwd)",target=/tmpdir \
    -e OMP_NUM_THREADS=4  \
    nicspalla/yambo-gcc_openmp_petsc:latest \
    yambo -F yambo.in -J yambo.out
 
Otherwise (suggested!), copy and paste the code below in a file, i.e called drun.sh:
 
#!/bin/bash
docker run -ti --user $(id -u):$(id -g) \
    --mount type=bind,source="$(pwd)",target=/tmpdir \
    -e OMP_NUM_THREADS=4  \
    nicspalla/yambo-gcc_openmp_petsc:latest $@
 
then give the file execute privileges:
 
chmod +x drun.sh
 
Move (or copy) this file in the directory where you want to use Yambo and use it as prefix of your Yambo calculation:
 
./drun.sh yambo -F yambo.in -J yambo.out
 
If the yambo container is working correctly you should obtain:
 
./drun.sh yambo
yambo: cannot access CORE database (SAVE/*db1 and/or SAVE/*wf)
 
./drun.sh yambo -h
 
should provide in output the help for yambo usage.

Setting up Yambo

In order to get the yambo code in your machine you have multiple options:

  • Yambo Virtual Machine
  • Yambo Container
  • Install the Yambo source in your computer

Setting up the Yambo Virtual Machine

The tutorials can be run on a dedicated Virtual Machine (called Yambo Quantum Mobile and adapted from the Quantum Mobile VM). This is run by installing it as Virtual Machine with the VirtualBox program. To install the Yambo VM in your computer you need to:

  • Download and install Virtualbox software
  • Download the Yambo Virtual Machine image
  • Install the Yambo Virtual Machine
  • Start the Yambo Virtual Machine
  • Update and install the Tutorials

To this end follow exactly the step listed here: Install the Yambo Quantum Mobile VM

Setting up the Yambo Container

- Install Yambo via Docker on your laptop / desktop

Install Yambo

If you have some experience with compiling codes, you can get the source and install it. If you never compiled a code, it is better to choose one of the above options as the technical assistance we can offer is limited.
