Brendan Gregg, unul dintre dezvoltatorii sistemului de depanare dinamic\u0103 DTrace, care lucreaz\u0103 \u00een prezent la Intel \u0219i dezvolt\u0103 instrumente pentru analiza performan\u021bei bazate pe eBPF \u00een nucleul Linux, a anun\u021bat deschiderea codului surs\u0103 pentru instrumentul iaprof (AI Flame Graphs). Instrumentul este destinat analizei informa\u021biilor despre performan\u021ba GPU Intel \u0219i vizualiz\u0103rii acestora. Codul este scris \u00een limbajul C \u0219i este disponibil sub licen\u021ba Apache 2.0. <\/p>\n

Platformele hardware accept\u0103 pl\u0103ci grafice Intel Arc bazate pe microarhitectura Battlemage (seria \u201eB\u201d), GPU-uri pentru centre de date din seria \u201eMax\u201d \u0219i diverse pl\u0103ci grafice Intel Xe2, printre altele, bazate pe iGPU Lunar Lake. Sistemul necesit\u0103 un nucleu Linux cu drivere actualizate pentru GPU-urile Intel (pentru Intel Battlemage este necesar un nucleu 6.15 \u0219i driver Xe, iar pentru Intel Max Series este suficient nucleul 5.15 \u0219i driverul i915). Nucleul Linux trebuie s\u0103 fie compilat cu interfe\u021bele specifice pentru driverele Intel, EU Stall \u0219i EU Debug. <\/p>\n

\u00cen profilurile colectate sunt reflectate \u00eent\u00e2rzierile \u00een func\u021bionarea blocurilor de execu\u021bie (Execution Unit), starea CPU \u0219i informa\u021bii despre nucleele GPU. Informa\u021biile colectate permit corelarea metricalor de performan\u021b\u0103 GPU cu codul executat pe CPU. \u00cen practic\u0103, instrumentul este convenabil de utilizat pentru analiza performan\u021bei jocurilor pe calculator \u0219i a aplica\u021biilor AI, care utilizeaz\u0103 intens GPU-ul, corel\u00e2nd utilizarea GPU cu executarea componentelor nucleului OS, bibliotecilor runtime \u0219i framework-urilor AI pe CPU. <\/p>\n

Rezultatele profil\u0103rii pot fi salvate \u00een format SVG pentru analiz\u0103 interactiv\u0103 \u00een browser (exemplu), folosind diagrame colorate \u201eFlameGraph\u201d \u0219i h\u0103r\u021bi \u201eFlameScope\u201d cu eviden\u021biere colorat\u0103 a problemelor. Graficele sunt interactive \u0219i permit m\u0103rirea detaliilor p\u00e2n\u0103 la cadrele stivei \u0219i instruc\u021biunile executate de GPU, vizualiz\u00e2nd detalii \u0219i efectueaz\u0103 opera\u021bii de c\u0103utare.
