Tianhe-2 - te rorohiko kaha tino i roto i te ao

Māngai o Mannheim University (Germany) tukuna he whakatauranga o te rorohiko tino kaha e te tīariari i runga i to tatou paraneta. Ko te rārangi ngā te katoa o e rima rau wae. E ai ki nga kairangahau, ina te tuhi i te reira ake he pūtake mō tenei ahua i tangohia rite te tere o te otinga o ngā whārite rārangi. I runga i nga raraunga whäkina, rite o tenei ra, te rorohiko kaha tino i roto i te ao - te reira Tianhe-2, i hanga e te pūtaiao Hainamana.

mahi rorohiko

I runga i nga hua «Linpack» te ünga, taea ki te mahi 33,86 trillion tātaitanga ia te rua o te wa tenei mīhini ko. Hoki tenei tohu, te rorohiko kaha tino i roto i te 2013 tata ma rima nga wa nui tona mua - Tianhe-1, i tuatahi faaite e pā ana ki toru tau ki muri. E ai ki Engineers Hainamana, kia rite ki te mahi mīharo o te whanaketanga tutuki e te whakamahi o pera-ka karanga tauira o parallelism tino. Kei te hāngai te reira i runga i te whakamahi o te maha o coprocessors Phi, ka e kia kōrero atu. Me kï reira e whakamahia he huarahi ōrite e maha atu ngā, nei whakaaro e ngā ano i roto i te whakatauranga.

Ā-"whakakī" taputapu

Ko wāhanga o 3.12 miriona otaota mai rorohiko kaha tino o te ao. Roto te pūrere mahi 32,000 Intel Xeon pūtukatuka me coprocessors 48 000 Xeon-Phi. Nā ki enei a i hanga ki runga ake i korero, maha o takitahi karihi fā'ūtaha tahi i roto i te rawa hangaia mō tenei whakaaro "TN-2 Express" hangarau. Ko te nui o te mahara, i whakahaere te Tianhe-2 he rite ki te kotahi petabyte. Ko te pūnaha whakahaere, te rorohiko kaha tino i roto i te ao mahi i runga i te Kylin Linux. kohi hiko o te pūrere 17.8 megawatts. Te nuinga o ngā mahi kamupene o te rorohiko (tae atu i te pūtukatuka, pūnaha whakahaere, interconnects, pūmanawa me te tono) whakawhanakehia, ka whakawhitia ki mooni i roto i China. Ko te okotahi anake ko te mana tukatuka o te mīhini, e ko te pūtake o maramara i Intel.

Wahi o te raruraru me te Scope

E ai ki nga ngā, te tīmatanga i mahara te rorohiko kaha tino i roto i te ao ki te tīmata i te 2015, ko ratou hiahia ki te whakatutuki i te hua pai arahina ki te whakaiti o te wā. I tēnei wā, ko te nohoanga o te pūrere ko te Hainamana University o hangarau ārai. Na tawhiti, whakahaere reira ngā whakamātautau e pā ana ki te matapae o ngā rerekētanga i roto i te āhuarangi, rerekē tātaitanga nui, me te te mahi o te pūrere i roto i ngā āhuatanga tino.

rorohiko atu kaha

Ki te titiro koe ki te tūranga, ka taea e kite koutou e kore anake te rorohiko kaha tino i roto i te ao, ko te whanaketanga Hainamana. I tua atu ki tona rārangi ano whakarārangitia 64 cars, i hanga nei e me te mahi i roto i tenei whenua. He nui o nga whakaaro tino kaha (ara, 253) e tohatoha i tenei wa i roto i te Hau Amui no Marite. He meka ngā, e pā ana ki te māngai o te rārangi, ko te meka e te maramara i Intel e whakamahia i konei i roto i te waru i roto o tekau take.
