Brendan Gregg, een van de ontwikkelaars van het dynamische debug-systeem DTrace, die momenteel bij Intel werkt en tools ontwikkelt voor prestatieanalyse op basis van eBPF in de Linux-kernel, heeft de open-sourcecode van de iaprof-toolkit (AI Flame Graphs) aangekondigd. De toolkit is bedoeld voor het analyseren van prestatie-informatie van Intel GPUs en de visuele representatie ervan. De code is geschreven in C en uitgebracht onder de Apache 2.0-licentie. <\/p>\n

Ondersteunde hardwareplatforms omvatten Intel Arc grafische kaarten gebaseerd op de Battlemage microarchitectuur (serie «B»), datacenter GPU's van de serie «Max» en diverse Intel Xe2 grafische kaarten, waaronder iGPU Lunar Lake. Het systeem vereist een Linux-kernel met recente stuurprogramma's voor Intel GPU's (voor Intel Battlemage is een kernel 6.15 en stuurprogramma Xe nodig, terwijl voor de Intel Max Series een kernel 5.15 en stuurprogramma i915 voldoende is). De Linux-kernel moet worden opgebouwd met de voor Intel stuurprogramma's specifieke interfaces EU Stall en EU Debug. <\/p>\n

In de verzamelde profielen worden de vertragingen in de werking van de Execution Units weergegeven, evenals de status van de CPU en informatie over de GPU-kernen. De verzamelde gegevens maken het mogelijk om prestatiemetingen van de GPU te koppelen aan de code die op de CPU wordt uitgevoerd. In de praktijk is de toolkit handig voor het analyseren van de prestaties van computerspellen en AI-toepassingen die intensief gebruik maken van de GPU, door de belasting op de GPU te vergelijken met de uitvoering op de CPU van OS-kerncomponenten, runtime-bibliotheken en AI-frameworks. <\/p>\n

Profileringsresultaten kunnen worden opgeslagen in SVG-formaat voor interactieve analyse in de browser (voorbeeld), met behulp van kleurrijke «FlameGraph» diagrammen en «FlameScope» kaarten die probleemgebieden benadrukken. De grafieken zijn interactief en stellen gebruikers in staat om in te zoomen op stack frames en uitgevoerde GPU-instructies, details te bekijken en zoekopdrachten uit te voeren.
