Cabling negatively affects not only the expandability of HPC systems, but also the reliability of their communications. In effect, the deployment of a supercomputer requires thousands of kilometers of cables, which are generally buried under the floor. Hence, moving or replacing these fibers is impossible once a supercomputer is deployed. In this study, we propose to exploit an efficient cabling method to enable multiple topologies in a system expanded incrementally. This approach reduces the cost of implementing an HPC system stage after stage, while requiring a limited knowledge about the future target applications and the final size of the system.
