| Abstract | The MIT Alewife project evolved out of exploratory work at Stanfordon directory schemesfor cachecoherence[1] (also includedin this issue). Using datafrom small bus-basedmultiprocessors, this earlywork demonstratedthatdirectoryschemeswere asefficient asbus-basedsnoopingprotocols,andthatby distributing directoriesalongwith main memory, they could provide the foundationsfor a cache-coherent shared-memorymultiprocessor basedon an interconnectionnetwork. This paperfurther recognizedthe scalinglimits of bit-vectordirectories– they consumed memoryproportionalto thesquareof thenumberof processors– andspeculatedthat variantssuchaslimited pointerdirectoriesor limited broadcast directories might beattracti ve scalablealternatives.Thepaper , however, stoppedshortof demonstratingthefeasibility of limited directories,largely becauseof the lack of either addresstracesor parallelprogramswritten for a scalablecoherent shared-memorysystem.This lackof datawasnotsurprisinggiven thatsucha machinehadnotbeeninventedyet! |
