Overview
Yakakwira Bandwidth Memory (HBM) yakarongedzerwa ndangariro yakaiswa padyo neGPU iyo inopa data nekukurumidza zvakanyanya kupfuura yakajairika RAM. Ndizvo zvinochengeta AI accelerators kudya, kudzivirira ane simba compute cores kubva pakugara zvisina basa ivo vakamirira maremu emhando uye data.
Yakakwira Bandwidth Memory inyanzvi yekuvaka inobata mhando yemhando, mutengo wezvivakwa, latency, uye kuvimbika pachiyero.
Deep Dive
HBM inogadzirisa bhodhoro rekutanga: yemazuva ano AI machipi anogona kuita matiririyoni ekushanda pasekondi, asi chete kana data rasvika nekukurumidza zvakakwana. Yakajairwa GDDR ndangariro inobatanidza pamusoro pebhazi rakatetepa, nepo HBM inorongedza akawanda DRAM inofa yakatwasuka uye inoabatanidza nezviuru zvemawaya madiki akatwasuka anonzi kuburikidza-silicon vias (TSVs). Aya masheki anogara pasilicon interposer millimeters kubva kuGPU, ichipa yakanyanyisa nzira yedata, funga zviuru zvebhiti kamwechete panzvimbo yemazana. Mhedzisiro ndeye bandwidth kuyerwa mumaterabytes pasekondi. Zvizvarwa zvafambira mberi kubva paHBM2 kuenda kuHBM2e, HBM3, uye HBM3e, chimwe nechimwe chichisimudza zvese zviri zviviri kugona nekumhanya. Kune mahombe emitauro mamodheru, ane huremu hunofanirwa kutenderedzwa nguva dzose, HBM huwandu uye bandwidth inowanzova yakakosha kupfuura komputa komputa.
Technical Insight
HBM inowana kumhanya kwayo kuburikidza nekunyanya kufanana kwete kukwirisa wachi. Nekumisikidza DRAM inofa uye nekuibatanidza nezviuru zveTSVs, inofumura yakafararisa interface (1024 bits per stack uye kumusoro), saka akawanda mabyte anofamba panguva imwe chete. Kuisa matanda pane yakagovaniswa interposer padivi peGPU inochengeta waya dziri pfupi, kucheka simba pabhiti uye latency. Iyo yekumhanyisa imwe chete senge NVIDIA H100 kana H200 pairi akati wandei HBM stacks kuti isvike akawanda terabytes pasekondi yehuwandu hwendangariro bandwidth.
Kubata High Bandwidth Memory
Yakakwira Bandwidth Memory (HBM) yakarongedzerwa ndangariro yakaiswa padyo neGPU iyo inopa data nekukurumidza zvakanyanya kupfuura yakajairika RAM. Ndizvo zvinochengeta AI accelerators kudya, kudzivirira ane simba compute cores kubva pakugara zvisina basa ivo vakamirira maremu emhando uye data. Yakakwirira Bandwidth Memory inyanzvi yekuvaka inobata mhando yemhando, mutengo wezvivakwa, latency, uye kuvimbika pachiyero. Kuti uvake kunzwisisa kwakadzama, bata High Bandwidth Memory semuenzaniso wekushandisa, kwete chinhu chimwe chete: tsanangura zvinodiwa, kujekesa fungidziro, uye patsanura izvo zvinogona kuitwa nehurongwa hwakavimbika kubva kune zvichiri kuda kutonga kwenyanzvi.
Mukuita, zvikwata zvakasimba zvinoshandisa High Bandwidth Memory inokwidziridza zvivakwa, data, uye sarudzo dzezvivakwa zvinopesana nekuvimbika uye mutengo. Ivo vanonyora zvakajeka maitiro ebudiriro, bvunzo vachipokana ne data rechokwadi uye mafambiro ebasa, uye iterate zvichibva pane zvakacherechedzwa maitiro ekutadza kwete kuhwina-nguva imwe chete yebhenji. Apa ndipo apo kunzwisisa kwe theoretical kunoshanduka kuve kugona kwakasimba pane chigadzirwa, mutemo, uye mashandiro.
Zvisarudzo zvezvivakwa zvinotyaira kuita uye mutengo wekushandisa kwemakore. Panguva imwecheteyo, Kukwirisa imwe bhenji kunogona kuvanza yakafara system kushaya simba. Nzira yakatsiga ndeyekubatanidza kukurumidza kuyedza nekutonga: mhanyisa vatyairi vendege, tora humbowo, buritsa matanda esarudzo, uye urambe uchivandudza chengetedzo semaitiro emuenzaniso, zvinotarisirwa nemushandisi, uye zvinodikanwa zvekutonga.
