Performance degradation analysis of a supercomputer

We analyze performance degradation phenomena due to software aging on a real supercomputer deployed at the Federico II University of Naples, by considering a dataset of ten months of operational usage. We adopted a statistical approach for identifying when and where the supercomputer experienced a performance degradation trend. The analysis pinpointed performance degradation trends that were actually caused by the gradual error accumulation within basic software of the supercomputer.
