Yintoni iTeraflop? IsiKhokelo esiPheleleyo seTFLOPS, iNtsebenzo, kunye neZicelo zeLizwe langempela

I. Intshayelelo

Ehlabathini le ukusebenza okuphezulu kwekhompyutha, igama elithile i-teraflop-okanye IFLOPS-Ngumlinganiselo obalulekileyo wekhompyuter amandla okubala. A i-teraflop imele ukukwazi ukwenza itriliyoni enye yemisebenzi edadayo ngesekhondi, iyenza ibe yindlela eqhelekileyo yokulinganisa ekrwada ukucubungula ukusebenza. Le metric isetyenziswa ngokubanzi ukuthelekisa CPUs, GPUs, kwaye nkqu iikhompyutha ezinkulu, ukuvumela iinjineli, abadlali, kunye nabaphandi ukuba baqonde ukuba ingakanani idatha inkqubo enokuyiqhuba ngexesha elithile.

Ukuqonda IFLOPS ibalulekile kuba inika ingqiqo kubuchule bomatshini bokuphatha compute-intensive workloads njenge:

• Ukulinganisa kwezenzululwazi (umzekelo wemozulu, amandla emolekyuli)

• Imidlalo kunye nonikezelo lwemizobo (ukulandelela imitha yexesha lokwenyani, imidlalo ye-4K)

• Kukubhadla okungeyonyani kwaye uqeqesho lokufunda ngoomatshini

• Uhlalutyo lwedatha enkulu kwaye cloud computing imisebenzi

Ngelixa isantya sewotshi (GHz) kunye Ubalo olungundoqo zisoloko zipapashwa, iiteraflops nika umfanekiso ocacileyo we ukusebenza kwinqanaba elidadayo, eyona nto ibalulekileyo kwizicelo ezifuna izibalo ezichanekileyo zemathematika. Eli nqaku liphonononga yintoni i-teraflop, zilinganiswa njani ii-TFLOPS, yabo usetyenziso lwehlabathi lokwenyani, kunye nentsingiselo yazo izixhobo zekhompyutha zale mihla-ukusuka kwiikhonsoli zokudlala ukuya iziko ledatha GPUs inika amandla i-AI.

II. Iziseko zeMisebenzi yeeNdawo eziNtandayo (FLOPS)

Embindini wokuqonda a i-teraflop ngumbono we IFLOPS-ImiSebenzi yeNqanaba elidadayo ngeSibini ngasinye. I-FLOP ilinganisa ukukwazi kwenkqubo yekhompyutha ukwenza enye ukubala indawo edadayo, njengokudibanisa, ukuthabatha, uphinda-phindo, okanye ukwahlula amanani okwenene anamanqaku edesimali. Ngenxa yokuba uninzi lwezicelo zanamhlanje-ezinje Ukulinganisa kwenzululwazi, Uqeqesho lwe-AI, kwaye Unikezelo lwe-3D-thembela kakhulu kwi-arithmetic yendawo edadayo, I-FLOPS ibe ngumgangatho wegolide yokulinganisa ukusebenza kwekhompyutha.

FLOPS Isimaphambili Solawulo

Izinto ezisisiseko ze-Arithmetic ezidadayo

Inombolo yendawo edadayo imelwe kusetyenziswa i IEEE-754 umgangatho, equka:

• Intwana yomqondiso (elungileyo okanye embi)

• Exponent (ubukhulu benani)

• UMantissa/Icandelo (iinkcukacha ezichanekileyo)

Eyahlukileyo amanqanaba achanekileyo kuchaphazela ukusebenza kunye nokuchaneka:

• FP64 (ichaneke kabini): Isetyenziswa kwi uphando lwenzululwazi apho ukuchaneka kubalulekile

• FP32 (echanekileyo-enye): Ixhaphakile ngaphakathi GPUs yomdlalo kunye nemizobo

• FP16 (isiqingatha-ngokuchanekileyo): Isetyenziswa kakhulu kwi I-AI kunye nokufunda koomatshini ukuphucula isantya kunye nokusebenza kakuhle

Kutheni FLOPS ibalulekile

Ngokungafaniyo isantya sewotshi (GHz) okanye Ubalo olungundoqo, ebonisa iinkcukacha zehardware ekrwada, I-FLOPS ibonisa ngokuthe ngqo umsebenzi wezibalo. Oku kwenza ukuba i-FLOPS ibaluleke kakhulu xa kuvavanywa Amaqela e-HPC, iziko ledatha GPUs, kwaye AI accelerators, apho ukusetyenzwa ngokunxuseneyo kwaye ukusebenza ngexesha lokwenyani zibalulekile.

III. Yintoni iTeraflops (TFLOPS)

A i-teraflop-idla ngokufinyezwa njenge IFLOPS-yindlela eqhelekileyo yokulinganisa ukusebenza kwekhompyutha. Igama liyadibanisa "oko" (intsingiselo iitriliyoni) kunye "flopha" (umsebenzi wendawo edadayo), emele ukukwazi komqhubekekisi okanye inkqubo yokwenza itriliyoni enye yemisebenzi edadayo ngesekhondi. Ngamanye amazwi, umatshini ulinganiswe ngo 1 TFLOP ingenza izibalo eziyi-1,000,000,000,000 ngomzuzwana ngamnye.

Umxholo kunye nentsingiselo esebenzayo

Kwiimeko zehlabathi, IFLOPS yi i-output metric, ayisosalathisi esingqalileyo sendlela “ikhawuleza” ngayo ikhompyutha evakalelwa ngayo. Kubaluleke kakhulu xa uvavanya i-hardware esebenzayo ukusetyenzwa ngokunxuseneyo, njenge:

• SPEC CPU -vavanya ukusebenza kwe-CPU kuyo yonke imisebenzi emininzi

• 3DMark / GFXBench – umlinganiselo I-GPU FLOPS ukusebenza kwemidlalo kunye nonikezelo

Iimpembelelo zokwenyani zeHlabathi

Ukuthelekisa izixhobo kuphela Iireyithingi ze-TFLOPS inokulahlekisa. I-GPU ene-TFLOPS eninzi isenokungaqhubi kakuhle ukuba ayanelanga imemori bandwidth okanye abaqhubi abangasebenziyo. Ngokufanayo, I-CPU FLOPS inokuthintelwa ngokuhambelana kwenqanaba lomyalelo okanye ubungakanani becache.

Kwiingcali kwi HPC, Uqeqesho lwemodeli ye-AI, okanye uphando lwenzululwazi, kubalulekile ukujonga iimetrikhi zokusebenza ezizinzileyo, ukusebenza kakuhle kwamandla, kunye umthwalo womsebenzi-ibenchmarks ezithile ukufumana umfanekiso ochanekileyo wenkqubo isakhono sokwenene sokubala. Ukuba ujonge ikhompyuter yeshishini kwimfuno yakho ephezulu yekhompyuter, nceda ucofe i-rackmount pc, pc elungisiweyo, njl.

V. Ukusetyenziswa kweeTeraflops

Ukubaluleka kwe IFLOPS idlulela ngaphaya kwengcamango—ixabiso layo lokwenene libonakala kuyo usetyenziso lwehlabathi lokwenyani apho kufuneka ugqitho olukhulu lokubala. Iinkqubo eziphezulu iireyithingi zeteraflop bagqwesileyo kwi ukusetyenzwa ngokunxuseneyo imisebenzi, ukunika amandla ukusungula kumashishini ukusuka kumdlalo ukuya uphando lwenzululwazi.

Imidlalo kunye nemizobo

Kwishishini lemidlalo, IFLOPS impembelelo ngqo ukusebenza kwemizobo kwaye amazinga esakhelo. GPUs nge TFLOPS ephezulu inokuqhubekeka ngakumbi iincam, pixels, kwaye izithunzi, yenza:

• Ixesha langempela lokulandelela imitha ukukhanyisa okufana nobomi

• Unikezelo lwe-4K kunye ne-8K kumazinga aphezulu efreyimu

• VR kunye AR amava nge-latency esezantsi

Umzekelo, i Xbox Series X (12 TFLOPS) kwaye I-PlayStation 5 (~10 TFLOPS) ukuhambisa umgangatho wemizobo ekufutshane-kwinqanaba lePC ngokusetyenziswa I-GPU ikhola amandla ilinganiswe ngeeteraflops.

Ubukrelekrele bokwenziwa kunye nokuFunda koomatshini

AI imithwalo yomsebenzi—ingakumbi uqeqesho lokufunda olunzulu-ifuna iitriliyoni ze Uphindaphindo lwematrix kwaye imisebenzi ye-vector. I-FLOPS ephezulu GPUs, njengeeNVIDIA A100 kwaye H100, hambisa amakhulu e-TFLOPS (FP16/FP8) ukukhawulezisa:
