ZhangYunquan,Secretary-GeneraloftheHighPerformanceComputingCommitteeoftheChineseComputerSociety,saidthat"Shenwei·TaihuLight"isthefirstsupercomputerintheworldbuiltwithdomesticprocessors.ItisbasedontheMinistryofScienceandTechnologyofthePeople'sRepublicofChina.Thedevelopmentcycleofthe863projecttooknearlythreeyears,butthepreviouspre-researchtimecouldnotbeestimated."Infact,weknewattheendoflastyearthatthe"ShenweiTaihuLight"hadtheabilitytowintheworldchampionship,butitwasoutofsecrecyatthetime.Considerthatithasnotbeenreleasedtotheoutsideworld."
Pokud jde o lokalizaci čínského superpočítačového centra, ZhangYunquans řekl, že podle hodnocení je lokalizace řady „Tianhe“ asi 70 % a superpočítač „ShenweiBlu-ray“ z celého Superpočítačového centra Jinan může dosáhnout více než 85 %.
