OSPRay kasutab ainult CPU v\u00f5imeid, mitte s\u00f5ltudes GPU-st, mis v\u00f5imaldab kasutada raamatukogu laias seadmete spektris, alates t\u00f6\u00f6jaamadest kuni klastrite s\u00f5lmedeni. Vajaduse korral kasutatakse aktiivselt mitme l\u00f5ime kasutamist ja vektoreerimist, toetades SIMD k\u00e4sklusi nagu Intel SSE4, AVX, AVX2 ja AVX-512 (OSPRay t\u00f6\u00f6ks on v\u00e4hemalt vajalik SSE4.1 tugi). <\/p>\n
