Umlo womthengi unyanzelisa abavelisi bekhontrakthi ye-semiconductor ukuba basondele ngakumbi kubaqulunqi. Olunye ukhetho lokuvumela abathengi abavela kwihlabathi lonke ukuba bazuze kwizixhobo eziqinisekisiweyo ze-EDA nazo zonke iinguqu zamva nje kukuhambisa iinkonzo kumafu oluntu. Kutshanje, impumelelo yale ndlela ibonakaliswe yinkonzo yokujonga i-topology yoyilo lwetshiphu, ebekwe kwiqonga leMicrosoft Azure yiTSMC. Isisombululo sisekwe kwisoftware yeCaliber nmDRC yangaphambili yeMentor Graphics, ngo-Epreli 2017 yi-Siemens yaseJamani.
njani kwi-AMD, ukujonga okupheleleyo kwe-topology (yomzimba). Kwimbali yenkampani, i-7nm Vega 20 GPU ene-13,2 yeebhiliyoni zee-transistors igqibe uyilo kwiiyure nje ze-10. Ukupasa okwesibini kuthathe enye iyure encinci. Ukupasa ezimbini kwiiyure ze-19 zovavanyo kwilifu sisiphumo esihle kakhulu, i-AMD iqinisekile. Oku kubonakalisa impumelelo yale ndlela kwaye kuvula amathuba amatsha kubaqulunqi: iimveliso ezintsha ziya kukwazi ukubonakala kwiimarike ngokukhawuleza kunye nokuphunyezwa okungcono.
Kuyathakazelisa ukuqaphela ukuba i-AMD Vega 20 GPU yavavanywa kwiqonga elikude kwi-AMD EPYC 7000 iiprosesa zechungechunge. Isoftware yeCaliber nmDRC yafakwa kwiicores ezingama-4410 okanye koomatshini abangama-69 (ngeyona bandwidth iphezulu yememori). Kumsebenzi omkhulu wenkumbulo njengokujonga i-topology yeprosesa, oku kubaluleke kakhulu.
Abaphuhlisi besoftware yeCaliber nmDRC nabo babe negalelo kwimpumelelo yeshishini. I-software ehlaziyiweyo ifuna i-50% yememori engaphantsi ukwenza imisebenzi yokuqinisekisa i-topology efanayo. Iqonga le-EPYC le-AMD, inkampani ithi, ihambisa i-33% ngaphezulu kwe-bandwidth kune-Intel enikezelayo. Ngokukodwa, kwinkonzo ye-Azure, i-memory subsystem isebenza ngesantya ukuya kuthi ga kwi-263 GB / s, kunye noomatshini be-HB-class virtual babonelela nge-80% ngaphezulu kwe-overput kuneeplatifti zefu ezikhuphisanayo.
