Brendan Gregg, einer der Entwickler des dynamischen Debugging-Systems DTrace, der derzeit bei Intel arbeitet und Tools zur Leistungsanalyse basierend auf eBPF im Linux-Kernel entwickelt, hat die Quelle des Tools iaprof (AI Flame Graphs) ver\u00f6ffentlicht. Dieses Tool dient zur Analyse von Leistungsinformationen der Intel-GPUs und deren anschaulicher Visualisierung. Der Code ist in C geschrieben und unter der Lizenz Apache 2.0 ver\u00f6ffentlicht. <\/p>\n

Die unterst\u00fctzten Hardware-Plattformen umfassen Intel Arc-Grafikkarten, die auf der Mikroarchitektur Battlemage (Serie \u00abB\u00bb), GPU f\u00fcr Rechenzentren der Serie \u00abMax\u00bb und verschiedene Intel Xe2-Grafikkarten basieren, unter anderem auf der iGPU Lunar Lake. Im System muss ein Linux-Kernel mit aktuellen Treibern f\u00fcr Intel GPUs vorhanden sein (f\u00fcr Intel Battlemage wird ein Kernel 6.15 und der Xe-Treiber ben\u00f6tigt, w\u00e4hrend f\u00fcr die Intel Max Series ein Kernel 5.15 und der i915-Treiber ausreichen). Der Linux-Kernel muss mit den spezifischen Intel-Treiber-Schnittstellen EU Stall und EU Debug kompiliert werden. <\/p>\n

In den gesammelten Profilen spiegeln sich die Latenzen der Execution Units (Ausf\u00fchrungseinheiten), der CPU-Zustand und Informationen \u00fcber die GPU-Kerne wider. Die gesammelten Daten erm\u00f6glichen es, Leistungskennzahlen der GPU mit dem Code, der auf der CPU ausgef\u00fchrt wird, zu verkn\u00fcpfen. In der Praxis ist das Tool n\u00fctzlich f\u00fcr die Analyse der Leistung von Computerspielen und KI-Anwendungen, die aktiv GPUs nutzen, indem die GPU-Last mit der Ausf\u00fchrung von OS-Kernkomponenten, Runtime-Bibliotheken und KI-Frameworks auf der CPU verglichen wird. <\/p>\n

Die Profilierungsergebnisse k\u00f6nnen im SVG-Format zur interaktiven Analyse im Browser gespeichert werden (Beispiel), wobei farbige Diagramme \u00abFlameGraph\u00bb und Karten \u00abFlameScope\u00bb verwendet werden, die problematische Bereiche farblich hervorheben. Die Diagramme sind interaktiv und erm\u00f6glichen das Vergr\u00f6\u00dfern bis hin zu Stack-Frames und den ausgef\u00fchrten GPU-Instruktionen, Details einzusehen und Suchoperationen durchzuf\u00fchren.
