Sharing scientific code - interactively - in the Cloud

Austria receives large EU-Grant to enable hosting interactive environments for collaborating and sharing high-performance-compute codes on GCP via the European Open Science Cloud. From fluid dynamics to quantum mechanical material research - wide ranges of scientific disciplines use complex and bespoke compute codes, that consume millions of cpu hours across thousands of parallel processors. Sharing these codes - e.g. with experts from other research groups - is tedious. Giving out the code alone doesn't solve the so-called -dependency hell-, meaning that the receiving group needs to spend significant time and nerves to acquire, build, compile and link all external (and sometimes arcane) dependencies and verify they work correctly on the new system. Unfortunately, this overhead measurably leads researchers to not even try sharing their code or comparing with foreign codes. Since sharing, comparing and learning from others are key constituents in discovery of complex solutions, the enablement of such scientific collaboration is a key problem to tackle and must not rest on the individual researchers- shoulders.
