I-AMD neCray kuleli sonto ukuthi ngo-2021 bazokwethula uhlelo lwe-supercomputer olukhiqiza kakhulu emhlabeni, olubizwa ngeFrontier. Kulindeleke impela ukuthi ikhasimende libe nguMnyango Wezamandla wase-US, nakuba umqondisi omkhulu we-AMD uLisa Su ephawula esisetshenziswa kuhlu lwemisebenzi enokuthula le khompuyutha enkulu okuzodingeka iyixazulule: ucwaningo lwebhayoloji, ukucacisa izakhi zofuzo, ukubikezela isimo sezulu kanye nokusesha imithombo emisha yamandla.
Abamele i-AMD banikeze ukuphawula okuthakazelisa kakhulu kubasebenzi besizindalwazi , okuvela kuyo ukuthi iziphi izingxenye ze-AMD ezilungiselelwe i-oda likaCray. Njengoba kubikiwe ngaphambilini, ikakhulukazi le phrojekthi i-AMD ayizange ithuthukise kuphela amaphrosesa amaphakathi e-EPYC, kodwa futhi nama-accelerator e-Radeon Instinct computing asekelwe kuma-GPU anenkumbulo ye-HBM (isizukulwane asicacisiwe).
Imfihlakalo yamaphrosesa amaphakathi we-supercomputer entsha
IPhini likaMongameli we-AMD uForrest Norrod akazange achaze ukuthi yimaphi ama-processor azoba yisisekelo se-Frontier supercomputer, kodwa ukubeke kwacaca ukuthi yimaphi ama-processor angeke asetshenziswe kuwo. Kusukela emazwini akhe, kuyaziwa ukuthi laba baprosesa ngeke basebenzise ukwakheka kweZen 2 kwamaphrosesa aseRoma alungiselelwa ukumenyezelwa engxenyeni yesithathu, noma ukwakhiwa kwesizukulwane esilandelayo okutholakala kumaphrosesa aseMilan, okufanele akhishwe ngo-2020. Amaphrosesa we-Frontier's EPYC azohlelwa ngokwezifiso. Yiqiniso, uLisa Su akakwazanga ukumelana nesilingo sokuchaza ukuthi amaphrosesa ale-supercomputer azosekelwe ekwakhiweni okuzothatha indawo yeZen 2. Kungacatshangwa ukuthi bazothola isakhiwo esiguquliwe seZen 3. Amaprosesa anjalo kufanele akhiqizwe kusetshenziswa okwesibili. -ubuchwepheshe besizukulwane se-7nm, obunezici zalokho okubizwa ngokuthi i-ultra-hard ultraviolet (EUV) lithography.
Kulo mongo, ngendlela, kuyacaca ukuthi inhloko ye-AMD yayicabanga ngobani engqungqutheleni yokubika yakamuva, isho ukuvela kwekhasimende elisha ngo-2020 lapho libheka izingxenye "zesiko", ezingahlangene ne ingxenye ye-console yokudlala. Kungacatshangwa ukuthi leli klayenti kungenzeka kube yi-Cray, ngoba ukunikezwa kwamaphrosesa kuzofanele kusungulwe ngaphambi kokuthi kwethulwe i-supercomputer ngo-2021.
UForrest Norrod wazivumela ukuba enze ihlaya ukuthi uma igama labacubunguli abakhethekile be-EPYC bephrojekthi yeFrontier lembulwa, kuzokhumbuza wonke umuntu ngelinye idolobha lase-Italy. Inkampani iqamba amaphrosesa weseva anezakhiwo zomndeni wakwaZen ukuhlonipha amadolobha ahlukahlukene ase-Italy: iNaples, iRoma noma iMilan.
Ingxenye yezithombe I-Frontier iphinde ifihle ukusebenzelana kwayo nezakhiwo
Endabeni yama-accelerator e-Radeon Instinct computing, i-AMD kuzodingeka futhi ivumelane nezidingo ze-Cray. Iwebhusayithi ye-Next Platform ibika ukuthi lezi zingxenye zeFrontier ngeke zisebenzise izakhiwo ze-Vega noma ze-Navi, kodwa zizokwakhiwa ngokwezifiso. Amasethi eziyalezo ezikhethekile azovumela ama-GPU ukuthi acubungule ngokushesha imisebenzi evamile yokulungiselelwa kweseva namasistimu obuhlakani bokwenziwa.
Ukunaka okukhethekile futhi kukhokhwa ekusebenzeni kahle kokudluliswa kwedatha phakathi kwamaphrosesa amaphakathi kanye namahluzo kulolu hlelo lwe-supercomputer. I-AMD ithuthukise isixhumi esibonakalayo se-Infinity Fabric enesivinini esikhulu. Kuzoba nama-graphic processors afika kwamane ngeprosesa emaphakathi.
Abamele i-Oak Ridge Laboratory, ezosebenzisa i-Frontier supercomputer, ngokwemibandela enembayo, bakwenza kwacaca kozakwabo abavela kuwebhusayithi ye-The Next Platform ukuthi izindleko zokuthenga ama-accelerator ekhompyutha ngenkumbulo ye-HBM sezidle ingxenye enkulu yesabelomali. ukwakhiwa kwezinhlelo zamakhompiyutha amakhulu. Kuze kube muva nje, i-AMD ikhuthaze ama-GPU ngenkumbulo ye-HBM ikakhulukazi engxenyeni yokusheshisa ihluzo, kodwa muva nje ibilokhu iwakhuthaza ngezidingo zokusheshisa ikhompuyutha. Ngekota yokuqala, kube ukuguquguquka okuhle kokulethwa kwezisheshisi ezinjalo ezisize i-AMD ikhuphule umkhawulo wayo wenzuzo kanye nenani elimaphakathi lokuthengisa lemikhiqizo yayo.
Esigabeni samakhompiyutha amakhulu, izisheshisi zekhompiyutha ze-NVIDIA Tesla zihlangabezane cishe nokumelana nokuncintisana, futhi lesi simo asizange sibe nomthelela omuhle kakhulu kunqubomgomo yamanani yale nkampani. Manje njengoba i-AMD isithole ukwesekwa okuqinile kubakhiqizi bamakhompiyutha amakhulu, amanani angase asondele emazingeni afanelekile, nakuba inkumbulo ye-HBM iqhubeka nokumba eqolo.
