1. Kungani Izinhlelo Zokuqeqesha ze-AI Zidinga Umlingani Okhethekile Wokwenza I-PCB Yeseva Yokuqeqesha ye-AI

Amaqoqo okuqeqesha e-AI awakhiwanga njengama-server ebhizinisi, futhi ama-PCB angaphakathi kwawo awakhiwanga njengama-PCB eseva yebhizinisi. Ukuqeqesha imodeli yolimi olukhulu olusemngceleni kungumsebenzi wenyanga yonke, othatha izigidi eziningi zamaRandi osebenza ezinkulungwaneni zama-GPU avumelaniswe ngokunemba kwe-microsecond. Iphutha elilodwa le-PCB kulelo qembu lingavimba lonke uhambo lokuqeqeshwa. Ezomnotho zenza ikhwalithi yokwenziwa kwe-PCB yeseva yokuqeqesha ye-AI kanye nobuqotho besignali kube yizinto ezibiza kakhulu eshidini lokwakha.

Inkinga yobuningi besignali ekwakhiweni kwe-PCB yeseva yokuqeqesha i-AI

Ibhodi lesisekelo lesimanje le-8-GPU lithwala ama-differential pair angaphezu kuka-1,000 asheshayo adlula izendlalelo ezingu-24-32 endaweni yebhodi engaba ngu-460 × 350 mm. Ibhodi lokushintsha le-InfiniBand NDR elingemuva ligxila ama-port angu-64 × 400G ku-chassis eyodwa, ngama-differential pair ayizinkulungwane eziningana ngebhodi ngalinye. Ibhodi lokushintsha lomgogodla le-1.6T liqhubekisela phambili lokho. Kuzo zonke izendlalelo, iminonjana yamazinga ahlukene ihambisana, eduze kwezinkomba ze-analog ezibucayi, ngokucindezela okuqhubekayo ukuze kulingane okuningi endaweni encane. Umlingani wokwakha i-PCB yeseva yokuqeqesha i-AI kumele abambe yonke ipharamitha ngaphansi kokulawula ngesikhathi esisodwa - hhayi eyodwa noma ezimbili kuphela.

Inkinga yesilinganiso sokubonisa

Ihadiwe yokuqeqesha ye-AI yamanje isebenza ku-112G PAM4 ngomzila ngamunye kokubili kokukhushulwa (NVLink) kanye nokukhushulwa (InfiniBand NDR, 800G Ethernet). Amapulatifomu esizukulwane esilandelayo athuthela ku-224G PAM4 ngomzila ngamunye. Ukuphindwa kabili kwesilinganiso sokubonisa kucindezela umkhawulo wesabelomali sokulahlekelwa, kudinga ukulawulwa okuqinile kokubhoboza emuva, futhi kwandisa umthelela wokugoba kwengilazi, ubulukhuni bomphezulu, kanye nokufakwa kwe-stub. Izinto ezisebenza ku-56G azinawo umkhawulo ku-112G; izinto ezisebenza ku-112G zisemkhawulweni wazo we-224G. Ukwenziwa kwe-PCB yeseva yokuqeqesha ye-AI kumele kuhambisane nesizukulwane ngasinye - ukuqhubekela phambili kwesilinganiso kumephu yethu yomgwaqo yamandla okukhiqiza i-PCB esheshayo.
