Brendan Gregg, l'un des d\u00e9veloppeurs du syst\u00e8me de d\u00e9bogage dynamique DTrace, travaillant actuellement chez Intel et d\u00e9veloppant des outils d'analyse de performance bas\u00e9s sur eBPF dans le noyau Linux, a annonc\u00e9 l'ouverture du code source de l'outil iaprof (AI Flame Graphs). Cet outil est destin\u00e9 \u00e0 analyser les informations de performance des GPU Intel et \u00e0 les visualiser de mani\u00e8re claire. Le code est \u00e9crit en langage C et est mis \u00e0 disposition sous la licence Apache 2.0. <\/p>\n

Les plateformes mat\u00e9rielles prennent en charge les cartes graphiques Intel Arc bas\u00e9es sur l'architecture micro-architecture Battlemage (s\u00e9rie \u00ab B \u00bb), les GPU pour centres de donn\u00e9es de la s\u00e9rie \u00ab Max \u00bb et diverses cartes graphiques Intel Xe2, notamment bas\u00e9es sur iGPU Lunar Lake. Le syst\u00e8me n\u00e9cessite un noyau Linux avec des pilotes r\u00e9cents pour les GPU Intel (un noyau 6.15 et le pilote Xe sont requis pour Intel Battlemage, tandis que pour la s\u00e9rie Intel Max, un noyau 5.15 et le pilote i915 suffisent). Le noyau Linux doit \u00eatre compil\u00e9 avec des interfaces sp\u00e9cifiques aux pilotes Intel telles que EU Stall et EU Debug. <\/p>\n

Les profils collect\u00e9s refl\u00e8tent les latences de fonctionnement des unit\u00e9s d'ex\u00e9cution (Execution Unit), l'\u00e9tat du CPU et des informations sur les c\u0153urs GPU. Les donn\u00e9es collect\u00e9es permettent de lier les m\u00e9triques de performance des GPU avec le code s'ex\u00e9cutant sur le CPU. En pratique, l'outil est utile pour analyser la performance des jeux vid\u00e9o et des applications d'IA qui utilisent intensivement les GPU, en comparant la charge sur le GPU avec l'ex\u00e9cution sur le CPU des composants du noyau OS, des biblioth\u00e8ques runtime et des frameworks d'IA. <\/p>\n

Les r\u00e9sultats du profilage peuvent \u00eatre enregistr\u00e9s au format SVG pour une analyse interactive dans le navigateur (exemple), utilisant des graphiques color\u00e9s \u00ab FlameGraph \u00bb et des cartes \u00ab FlameScope \u00bb mettant en \u00e9vidence les points probl\u00e9matiques par couleur. Les graphiques sont interactifs et permettent de zoomer sur les d\u00e9tails jusqu'aux cadres de la pile et aux instructions ex\u00e9cut\u00e9es par le GPU, de visualiser les d\u00e9tails et d'effectuer des op\u00e9rations de recherche.
