Bubble Tool

Emulate the Performance Degradation due to Faults in Real Hardware


The aim of Bubble Tool is to emulate the performance degradation due to periodic appearance of faults with a given mean time to repair (MTTR) and mean time to failure (MTTF) in Real Hardware. This is done by co-running the application of interest with Bubble (stress test program) which is tuned to periodically stress the shared resources depending on the MTTR & MTTF values.

This tool has been developed by Lorena Ndreu.

The research leading to this tool is supported by the European Commission FP7 project "Harnessing Performance Variability" (Project No:612069 "HARPA")
