Brendan Gregg, uno de los desarrolladores del sistema de depuraci\u00f3n din\u00e1mica DTrace, que actualmente trabaja en Intel y desarrolla herramientas para el an\u00e1lisis del rendimiento basadas en eBPF en el n\u00facleo de Linux, ha anunciado la apertura del c\u00f3digo de la herramienta iaprof (AI Flame Graphs). Esta herramienta est\u00e1 destinada al an\u00e1lisis de informaci\u00f3n sobre el rendimiento de las GPU de Intel y su visualizaci\u00f3n gr\u00e1fica. El c\u00f3digo est\u00e1 escrito en C y se encuentra bajo la licencia Apache 2.0. <\/p>\n

Las plataformas de hardware compatibles incluyen las tarjetas gr\u00e1ficas Intel Arc basadas en la microarquitectura Battlemage (serie \u00abB\u00bb), los GPU para centros de datos de la serie \u00abMax\u00bb y varias tarjetas gr\u00e1ficas Intel Xe2, entre otras, basadas en iGPU Lunar Lake. El sistema requiere un n\u00facleo de Linux con controladores actualizados para GPU Intel (para Intel Battlemage se necesita el n\u00facleo 6.15 y el controlador Xe, mientras que para la serie Intel Max es suficiente con el n\u00facleo 5.15 y el controlador i915). El n\u00facleo de Linux debe ser compilado con interfaces espec\u00edficas de los controladores Intel: EU Stall y EU Debug. <\/p>\n

Los perfiles recopilados reflejan las latencias en el funcionamiento de las Unidades de Ejecuci\u00f3n (Execution Unit), el estado de la CPU y la informaci\u00f3n sobre los n\u00facleos de la GPU. Los datos recopilados permiten relacionar las m\u00e9tricas de rendimiento de la GPU con el c\u00f3digo que se ejecuta en la CPU. En la pr\u00e1ctica, la herramienta es conveniente para analizar el rendimiento de los videojuegos y aplicaciones de IA que utilizan activamente la GPU, comparando la carga en la GPU con la ejecuci\u00f3n de los componentes del n\u00facleo del sistema operativo, bibliotecas runtime y frameworks de IA en la CPU. <\/p>\n

Los resultados del perfilado se pueden guardar en formato SVG para an\u00e1lisis interactivo en el navegador (ejemplo), utilizando gr\u00e1ficos en colores \u00abFlameGraph\u00bb y mapas \u00abFlameScope\u00bb que resaltan en color los puntos problem\u00e1ticos. Los gr\u00e1ficos son interactivos y permiten aumentar el detalle hasta los cuadros de pila y las instrucciones ejecutadas por el GPU, visualizar los detalles y realizar operaciones de b\u00fasqueda.
