Abstract [en]

In large complex server-like computer systems it is difficult to characterise hardware usage in early stages of system development. Many times the applications running on the platform are not ready at the time of platform deployment leading to postponed metrics measurement. In our study we seek answers to the questions: (1) Can we use a feedback-based control system to create a characteristics model of a real production system? (2) Can such a model be sufficiently accurate to detect characteristics changes instead of executing the production application? The model we have created runs a signalling application, similar to the production application, together with a PID-regulator generating L1 and L2 cache misses to the same extent as the production system. Our measurements indicate that we have managed to mimic a similar environment regarding cache characteristics. Additionally we have applied the model on a software update for a production system and detected characteristics changes using the model. This has later been verified on the complete production system, which in this study is a large scale telecommunication system with a substantial market share.
