System wymaga j\u0105dra Linux z aktualnymi sterownikami dla GPU Intel (dla Intel Battlemage wymagane jest j\u0105dro 6.15 i sterownik Xe, a dla Intel Max Series wystarczy j\u0105dro 5.15 i sterownik i915). J\u0105dro Linux musi by\u0107 zbudowane z interfejsami specyficznymi dla sterownik\u00f3w Intel: EU Stall i EU Debug. <\/p>\n

W praktyce narz\u0119dzie jest wygodne do analizy wydajno\u015bci gier komputerowych i aplikacji AI, kt\u00f3re intensywnie wykorzystuj\u0105 GPU, por\u00f3wnuj\u0105c obci\u0105\u017cenie GPU z dzia\u0142aniem na CPU komponent\u00f3w j\u0105dra systemu operacyjnego, bibliotek runtime i framework\u00f3w AI. <\/p>\n
