Running pipelines at scale on HPC facilities

In this talk I will give an account of a project we carried out to optimise and rework a pipeline to run at scale on a high performance computing facility while still remaining portable enough to run elsewhere. I’ll go into details of how we measure performance and scalability and go through the steps that were taken to lower the cost of running the pipeline. Finally, I’ll cover some of the problems that became apparent only when the pipeline went into production.
