Inthisscenario,performanceevaluationplaysacentralrole. Performance evaluationhastoassessandpredicttheperformanceofhardwareandsoftware systems,andtoidentifyandpreventtheircurrentandfutureperformancebo- lenecks. Inthepastthirtyyears,manyperformanceevaluationtechniquesandtools havebeendevelopedandsuccessfullyappliedinstudiesdealingwiththec- gurationandcapacityplanningofexistingsystemsandwiththedesignand developmentofnewsystems. Recently,performanceevaluationtechniqueshave evolvedtocopewiththeincreasedcomplexityofthecurrentsystemsandtheir workloads. Manyoftheclassicaltechniqueshavebeenrevisitedinlightofthe recenttechnologicaladvances,andnoveltechniques,methods,andtoolshave beendeveloped. Thisbookisorganizedaroundasetofsurveypaperswhichprovideac- prehensiveoverviewofthetheories,techniques,andtoolsforperformanceand reliabilityevaluationofcurrentandnewemergingtechnologies. Thepapers,by leadinginternationalexpertsinthe eldofperformanceevaluation,arebasedon thetutorialspresentedattheIFIPWG7. 3InternationalSymposiumonCom- terModeling,Measurement,andEvaluation(Performance2002)heldinRome onSeptember23 27,2002.
