Significanceofdevelopment
ZhangYunquan,Secretary-GeneraloftheHighPerformanceComputingCommitteeoftheChineseComputerSociety,saidthat"Shenwei·TaihuLight"isthefirstsupercomputerintheworldbuiltwithdomesticprocessors.ItisbasedontheMinistryofScienceandTechnologyofthePeople'sRepublicofChina.Thedevelopmentcycleofthe863projecttooknearlythreeyears,butthepreviouspre-researchtimecouldnotbeestimated."Infact,weknewattheendoflastyearthatthe"ShenweiTaihuLight"hadtheabilitytowintheworldchampionship,butitwasoutofsecrecyatthetime.Considerthatithasnotbeenreleasedtotheoutsideworld."
AsforthelocalizationofChina’ssupercomputing,ZhangYunquansaidthataccordingtotheassessment,thelocalizationofthe“Tianhe”seriesisabout70%,andthe“ShenweiBlu-ray”supercomputeroftheJinanSupercomputingCentercanreachOver85%,theprocessorof"ShenweiTaihuLight"isproducednationwide.
