Earth Simulator (tsara ta farko)

  Tsararren farko na Earth Simulator, wanda gwamnatin Japan ta kirkira ta hanyar shirin "Earth Simulator Project", tsarin kwamfuta ne mai kama da juna don gudanar da samfuran yanayi na duniya don kimanta Tasirin dumamar duniya da matsaloli a cikin ilimin ƙasa mai ƙarfi. An haɓaka tsarin ne don Hukumar Binciken Aerospace ta Japan, Cibiyar Binciken Makamashi ta Japan, da Cibiyar Kimiyya da Fasaha ta Japan (JAMSTEC) a cikin shekara ta 1997. Ginin yafara ne a watan Oktoba na shekara ta 1999, kuma an buɗe shafin a hukumance a ranar 11 ga Maris 2002. Aikin ya kai yen biliyan 60.

Ginin NEC, ES ya dogara ne akan tsarin su na SX-6. Ya kunshi nodes 640 tare da masu sarrafawa takwas da gigabytes 16 na ƙwaƙwalwar ajiyar kwamfuta a kowane node, don jimlar masu sarrafawa 5120 da 10 terabytes na ƙwaƙwalwa. An shigar da nodes biyu a kowace mita 1 × mita 1.4 × mita 2 cabinet. Kowace majalisa ta cinye 20 kW na wutar lantarki.  Tsarin yana da 700 terabytes na ajiyar faifai (450 don tsarin da 250 ga masu amfani) da 1.6 petabytes na ajiyar taro a cikin tafiyar tef. Ya sami damar gudanar da kwaikwayon yanayi na duniya a cikin yanayi da teku har zuwa ƙuduri na kilomita 10.  Ayyukanta a kan ma'auni na LINPACK shine 35.86 TFLOPS, wanda ya kusan sau biyar da sauri fiye da kwamfuta mafi sauri na baya, ASCI White.

ES itace kwamfuta mafi sauri a duniya daga 2002 zuwa 2004. IBM ta Blue Gene/L / L prototype ta wuce ƙarfinta a ranar 29 ga Satumba 2004.

An maye gurbin ES da Earth Simulator 2 (ES2) a watan Maris na shekara ta 2009. ES2 tsarin NEC SX-9 / E ne, kuma yana da kwata kamar yadda nodes da yawa kowannensu na 12.8 sau da yawa na aikin (3.2 × saurin agogo, sau hudu na kayan aiki a kowane node), don babban aikin 131 TFLOPS. Tare da aikin LINPACK na 122.4 TFLOPS, ES2 itace mafi inganci a duniya a wannan lokacin. A watan Nuwamba na shekara ta 2010, NEC ta bada sanarwar cewa ES2 ta hau kan Global FFT, ɗaya daga cikin matakan HPC Challenge Awards, tare da lambar aikin 11.876 TFLOPS.

  ES2 an maye gurbin ta da Earth Simulator 3 (ES3) a watan Maris na shekara ta 2015. ES3 tsarin NEC SX-ACE ne tare da nodes 5120, kuma aikin 1.3 PFLOPS.

ES2 an maye gurbin ta da Earth Simulator 3 (ES3) a watan Maris na shekara ta 2015. ES3 tsarin NEC SX-ACE ne tare da nodes 5120, kuma aikin 1.3 PFLOPS., daga 2017 zuwa 2018, ya gudana tare da Gyoukou, babban kwamfuta tare da sanyaya mai nutsewa wanda zai iya cimma har zuwa 19 PFLOPS.
