Note them down as **you will need them**. - Access via ssh - Shell access: `ssh -t <username>@vmos.vsc.ac.at l55` - You will be connected to the specfic login node `l55` so you will need to enter your password twice, and you may also be required to enter an OTP - EESSI demo GitHub repo: https://github.com/EESSI/eessi-demo `git clone https://github.com/EESSI/eessi-demo.git` - EESSI workflow demo GitHub repo: https://github.com/EESSI/eessi-nextflow-example - `git clone https://github.com/EESSI/eessi-nextflow-example.git` - Enter repository: `cd eessi-nextflow-example` - Setup direnv: `eval "$(direnv hook bash)"` - Allow direnv in dir: `direnv allow` - Run the workflow: `./hello_plus_version.nf` - I believe this step had to be done before running direnv ```bash srun --time 150 --ntasks 1 --cpus-per-task 8 --mem=20G --partition=zen3_0512 --hint=nomultithread --qos=zen3_0512 --reservation=eessi_training --pty /bin/bash ``` ### Additional info - **[Tutorial slides](https://docs.google.com/presentation/d/1SU5ujgz0JBKM0lLack8HyEcDcjQF6STyNTZ9n85n1MA/edit?usp=sharing)** - [EESSI documentation](https://www.eessi.io/docs/) - Initialising the EESSI environment ```bash source /cvmfs/software.eessi.io/versions/2023.06/init/lmod/bash ``` ### Communicating with us It's preferred to use Slack so that you can also join the EESSI community (and have quick access to all those using and contributing to EESSI!): * To join the EESSI Slack: https://join.slack.com/t/eessi-hpc/shared_invite/zt-1wqy0t8g6-PZJTg3Hjjm5Fm3XEOkzECg . * For posting questions or comments related to the tutorial during the presentations, we strongly prefer you to join the `#eessi-tutorial` channel in the EESSI Slack (direct link: https://eessi-hpc.slack.com/archives/C068ACS7XK8 ) * During the hands-on sessions you will be placed in break-out rooms which are _not_ recorded. This is a good opportunity to talk directly to the tutorial helpers to raise specific issues. Issues that might be of general interest will be re-raised in the main room by the helper. ### Feedback - [Workshop feedback form](https://events.vsc.ac.at/event/141/surveys/140) ### Accessing EESSI repositories * **production** EESSI repository: ```bash unset MODULEPATH source /cvmfs/software.eessi.io/versions/2023.06/init/bash ``` or ```bash unset MODULEPATH source /cvmfs/software.eessi.io/versions/2023.06/init/lmod/bash ``` --- ### Code of conduct During this tutorial, we strive to follow the [Contributor Covenant Code of Conduct](https://www.contributor-covenant.org/version/2/1/code_of_conduct/) to foster an inclusive and welcoming environment for everyone.
