Is the Supercomputer service the right choice?

The Supercomputer system is only an efficient choice if your research workflow requires at minimum 128 CPUs/cores at a time.

If you do not use at least 128 CPUs/cores at a time, or if you're unsure whether this level of resources would be helpful, you should first benchmark your workflow via the ScienceCloud or the ScienceCluster.
