linus torvalds Akahluzi mazwi futhi uvamise ukukhuluma ngokuzwakalayo nangokucacile ngalokho akucabangayo ngezinye zezinto. Ngalesi sikhathi unqume ukusho ukuthi ucabangani nge-Intel AVX-512 set set. Isethi yemiyalo engezwe ngaphezulu kwesisekelo x86-64 ISA ukuhlinzeka ngemiyalo yokubala eyenzelwe ngokukhethekile izindawo ze-HPC.
Empeleni le miyalo kufanele ibe mihle, empeleni ingeza ukusebenza kwezinhlobo ezithile zezinhlelo zokubala ezisetshenziswe ezindaweni ze-HPC. Kepha iLinus Torvalds ayithandanga ukuthi le sethi yemiyalo ifakiwe kuma-processor we-Intel desktop. Eqinisweni, kubonakala sengathi i-Intel isicubungule kabusha futhi kubonakala sengathi ikusasa labo I-Alder Lake ngeke ibe nokuxhaswa kwe-AVX-512.
ILinus Torvalds inombono wokuthi kufanele bagxile kakhulu kulokho okubaluleke kakhulu kulolu hlobo lwesigaba kunokumosha izinsiza kuzinhlelo zokufundisa ezintsha ezinjenge-AVX-512 ezingasho lutho. Ngaphandle kwemakethe i-HPC (Ukusebenza Okuphezulu Kwekhompiyutha).
Njengoba i-AVX-512 iqale ku- I-Xeon Phi x200 (Knights Landing), bese idlulela eSkylake-SP, Skylake-X, Cannon Lake naseCascade Lake. Ngemuva kwalokho, abanye abafana neCooper Lake ne-Ice Lake baphinde basekela izihlokwana ezithile zemiyalo evela ku-repertoire ye-AVX-512.
La umbono othunyelwe nguPhoronix weLinus Torvalds ayinadoti:
Ngiyethemba ukuthi i-AVX512 ifa kabuhlungu, nokuthi i-Intel iqala ukulungisa izinkinga zangempela esikhundleni sokuzama ukudala imiyalo yomlingo bese idala izilinganiso ezingabukeka kahle kuzo.
Ngiyethemba i-Intel ibuyela kuzisekelo - yenza inqubo yakho iphinde isebenze futhi ugxile kakhulu kukhodi ejwayelekile engeyona ye-HPC noma elinye icala elikhethekile elingenangqondo.
Ngikushilo lokhu ngaphambilini, futhi ngizokusho futhi: ngosuku lwe-x86, lapho i-Intel ibulala wonke umncintiswano, impela wonke umuntu wenza kangcono kune-Intel e-FP (Float-Point) imithwalo. Ukusebenza kwe-Intel's FP kwamunca (ukukhuluma ngokuqhathaniswa), futhi kwakungakhathalekile iota eyodwa.
Ngoba akekho umuntu owayekhathalela ngaphandle kwamabhentshi.
Lokhu kunjalo ikakhulukazi nge-AVX512 manje, nasesikhathini esizayo. Yebo, ungathola izinto ezibalulekile kuwe. Cha, lezo zinto azithengisi imishini esithombeni esikhulu.
Futhi i-AVX512 inezinto ezingezansi zangempela. Ngingathanda ukubona isabelomali se-transistor sisetshenziswa kwezinye izinto ezifaneleke kakhulu. Noma kuseyizibalo ze-FP (kwi-GPU, esikhundleni se-AVX512). Noma vele unginike ama-cores amaningi (ngokusebenza okuhle okukodwa, kepha ngaphandle kukadoti ofana ne-AVX512) njengoba kwenza i-AMD. (Khumbula ukuthi manje iLinus isebenzisa i-AMD Threadripper kwi-PC yayo)
Ngifuna imingcele yam amandla ifinyelelwe ngekhodi ejwayelekile ephelele, hhayi ngegciwane lamandla le-AVX512 elisusa imvamisa ephezulu. Njengoba leyo junk engenamsebenzi ithatha isikhala futhi isuse ama-cores.
Uma ngibona. Ngitadisha ngokuphelele izilinganiso ze-FP futhi ngiyabona ukuthi abanye abantu banendaba kakhulu. Ngicabanga nje ukuthi i-AVX512 yinto okungeyona okufanele yenziwe. Kuwukuzilibazisa kwami. Kuyisibonelo esihle sento eyenziwe yi-Intel, ngokwengxenye ngokwandisa ukuhlukaniswa kwemakethe.
[…] Yenza i-FPU eyanele ngokwanele, futhi abantu bazojabula. I-AVX2 ingaphezu kokwanele.
Yebo, nami ngiyavumelana noLinus. I-Intel ihlale ikhombisa okuthile okuhle kancane. Mhlawumbe ngoba incike kakhulu ekumaketheni. Kepha ukube ubunesifiso sangempela, ngabe usuvele ufake ubuchwepheshe be-nano, obunamakhokho amaningi. Noma kunjalo, konke lokhu kuzodala ukuthi izinkampani ezintsha zivele zenze lokho i-Intel engafuni ukukwenza.
Ama-Intel anamasethi wawo wokufundisa aphathelene akuyona i-Intel-igent kakhulu.
