Title
Impact of Cache Coherence Protocols on the Processing of Network Traffic
Abstract
Sincetheintroductionofthe10GbEstandardin2002,theabilityofgeneralpurposeprocessorstoefficientlyprocessnetworktrafficwithcommonprotocolssuchasTCP/IPhasbeenrevisitedandcriticallyevaluated.However,recentcommerciallyavailableprocessorssuchasIntel®CoreTM2DuoProcessor introduce microarchitectural enhancementsthatcouldsignificantlyinfluencetheapproachtoacceleratingnetworkprocessing.WeexaminethenetworkperformanceofarealplatformcontainingIntel®CoreTMmicro-architecturebasedprocessors,the role of coherency and a prototype implementationofdirectcacheplacement(DirectCacheAccessorDCA)ofinboundnetworktraffic.Weobservethatasubstantialportionofthetimerelatestotheinefficiency of I/O specific coherence protocols in theplatform.Wedemonstratethatarelatively,lowcomplexityimplementationofDCAcalled`PrefetchHint'providesa15to43%speed-uptoreceive-sideprocessingacrossarangeofI/Osizesandpresentadetailed characterization of the benefits.
