It&#x27;s important to recognise that a lot of the model runs are done on super-computers, and the runs themselves aren&#x27;t always easy to replicate from a practical point of view, because of things like resource limitations and configuration issues.<p>I certainly agree that things should be open sourced, probably allowing for some kind of embargo system for publication, but we shouldn&#x27;t allow a rhetoric to develop suggesting that people should be making things easily replicable, because that essentially means making very portable and resource-flexible code, which is not trivial, even in less complex domains, as I&#x27;m sure many people on this forum recognise.<p>As an example, many models make use hundreds of cores via MPI (along with preposterous amounts of RAM), and whilst I am no expert, I get the impression that porting such things to more commodity hardware is essentially impossible.<p>As an aside, I have seen more bad-faith practice (i.e. manipulation of results) in industry than in science, and have spent approximately equal periods of time in both.
