Ubuntu \u00fcleminek otsustas vaikimisi pakkuda intel-compute-runtime paketti, mis on kokku pandud NEO_DISABLE_MITIGATIONS lippudega, mis keelab Spectre r\u00fcnnakute kaitse. Ubuntu arendajate hinnangul toob sarnane kaitse kaasa paketi j\u00f5udluse languse ligikaudu 20%. <\/p>\n

Intel-compute-runtime pakett sisaldab komponente, mis on vajalikud OpenCL ja OneAPI Level Zero kasutamiseks Intel GPU-dega s\u00fcsteemides. Paketi kohaletoimetatavate teegide koostamisel toob NEO_DISABLE_MITIGATIONS koostamislipu olemasolu kaasa kompilaatori valikute «-mretpoline -mindirect-branch=thunk -mfunction-return=thunk -mindirect-branch-register» keelamise, mis tagavad t\u00e4iendava kaitse Spectre'i vastu. Need valikud ei m\u00f5juta OpenCL ja GPU-l tehtud operatsioonide j\u00f5udlust, kuid v\u00e4hendavad API t\u00f6\u00f6 eest vastutava koodi t\u00e4itmise kulusid. <\/p>\n

Intel ja Canonicali turbeinsenerid arutasid ning j\u00f5udsid j\u00e4reldusele, et Spectre kaitse, mis on rakendatud Compute Runtime tasemel, ei ole enam vajalik, kuna vajalik kaitse on juba olemas tuumatasandil. Compute Runtime'i olemasolev Spectre kaitse on peamiselt huvitav neile, kes kasutavad tuumasid, millel puudub piisav kaitse, ja kasu sellest ei \u00fcleta t\u00e4heldatud j\u00f5udluse langust. Lisaks on Intel Graphics Compute Runtime'i v\u00e4ljaanded kogutud vaikevalikuga NEO_DISABLE_MITIGATIONS, mis keelab kaitse.
