Dear Einstein Toolkit team, I hope this message finds you well. I am a beginner with the Einstein Toolkit. On personal workstations I have been able to compile and run tutorial simulations at low resolution, but I am facing problems on two different clusters. I would like to ask two questions:
1. *Are there ET versions prior to 2022_05 (e.g. 2019–2020 releases) that can still be downloaded and compiled successfully?* When I try to fetch them from the website using ./GetComponents, the process fails (CactusSourceJar.git is not created and some components do not download). Since some of the nodes I use have older GCC versions (8 or 10) and limited modules, a stable older release might be more practical. 2. During compilation, I notice that thorns (such as GSL and HDF5, for example) fall back to using the bundled versions because system modules are not found. The build completes successfully, but jobs fail immediately after submission to PBS or SLURM queues. *What is the role of the bundled versions in this case*?* If the build uses bundled GSL/HDF5, do I still need to load corresponding, compatible modules in the runscript?* Could this mismatch explain why jobs die right after submission? Any advice on handling these issues would be very helpful. Thank you very much for your time and support. Greetings, O.V.
