Brendan Gregg, en af udviklerne af DTrace-systemet til dynamisk fejlfinding, der nu arbejder hos Intel og udvikler v\u00e6rkt\u00f8jer til ydeevneanalyse baseret p\u00e5 eBPF i Linux-kernen, har annonceret frigivelsen af iaprof v\u00e6rkt\u00f8jets kildekode (AI Flame Graphs). V\u00e6rkt\u00f8jet er designet til at analysere information om Intel GPU-ydeevne og dens visuelle repr\u00e6sentation. Koden er skrevet i C og er open source under Apache 2.0-licensen. <\/p>\n

De underst\u00f8ttede hardwareplatforme inkluderer Intel Arc grafikkort baseret p\u00e5 mikroarkitektur Battlemage (serien \u201eB\u201c), datacenter GPU'er i serien \u201eMax\u201c og forskellige Intel Xe2 grafikkort, herunder dem baseret p\u00e5 iGPU Lunar Lake. Systemet kr\u00e6ver en Linux-kerne med opdaterede drivere til Intel GPU'er (for Intel Battlemage kr\u00e6ves kerne 6.15 og Xe-driveren, mens en kerne 5.15 og i915-driveren er tilstr\u00e6kkelig for Intel Max Series). Linux-kerne skal v\u00e6re samlet med Intel-specifikke gr\u00e6nseflader som EU Stall og EU Debug. <\/p>\n

De indsamlede profiler viser latency i execution units (Execution Unit), CPU-status og information om GPU-kernerne. De indsamlede data muligg\u00f8r forbindelse mellem GPU-ydeevnemetrier og koden, der k\u00f8rer p\u00e5 CPU'en. Praktisk set er v\u00e6rkt\u00f8jet nyttigt til at analysere ydeevnen i computerspil og AI-applikationer, der aktivt bruger GPU, ved at sammenligne GPU-belastningen med CPU-komponenternes eksekvering i OS-kernen, runtime-bibliotekerne og AI-rammev\u00e6rker. <\/p>\n

Profilingresultaterne kan gemmes i SVG-format til interaktiv analyse i browseren (eksempel), ved hj\u00e6lp af farvede diagrammer som \u201eFlameGraph\u201c og kortene \u201eFlameScope\u201c, der fremh\u00e6ver problemomr\u00e5der med farve. Grafikkerne er interaktive og g\u00f8r det muligt at zoome ind p\u00e5 detaljer som stakframes og udf\u00f8rte GPU-instruktioner, se detaljer og udf\u00f8re s\u00f8geoperationer.
