Brendan Gregg, uno degli sviluppatori del sistema di debug dinamico DTrace, attualmente impiegato presso Intel e impegnato nello sviluppo di strumenti per l'analisi delle prestazioni basati su eBPF nel kernel Linux, ha annunciato l'apertura del codice sorgente dello strumento iaprof (AI Flame Graphs). Questo strumento \u00e8 progettato per analizzare le informazioni sulle prestazioni delle GPU Intel e visualizzarle in modo chiaro. Il codice \u00e8 scritto in linguaggio C ed \u00e8 aperto sotto licenza Apache 2.0. <\/p>\n

Tra le piattaforme hardware sono supportate le schede grafiche Intel Arc basate sull'architettura micrografica Battlemage (serie \u201cB\u201d), le GPU per data center della serie \u201cMax\u201d e varie schede grafiche Intel Xe2, tra cui quelle basate su iGPU Lunar Lake. \u00c8 necessario un kernel Linux con i driver aggiornati per le GPU Intel (per Intel Battlemage \u00e8 richiesto il kernel 6.15 e il driver Xe, mentre per la serie Intel Max \u00e8 sufficiente il kernel 5.15 e il driver i915). Il kernel Linux deve essere compilato con le interfacce specifiche per i driver Intel EU Stall e EU Debug. <\/p>\n

Nei profili raccolti vengono registrate le latenze di funzionamento delle unit\u00e0 di esecuzione (Execution Unit), lo stato della CPU e informazioni sui core della GPU. I dati raccolti permettono di collegare le metriche delle prestazioni della GPU con il codice eseguito sulla CPU. Nella pratica, lo strumento \u00e8 utile per analizzare le prestazioni dei giochi e delle applicazioni AI che fanno uso intensivo delle GPU, confrontando il carico della GPU con l'esecuzione sulla CPU dei componenti del kernel del sistema operativo, delle librerie runtime e dei framework AI. <\/p>\n

I risultati del profiling possono essere salvati in formato SVG per un'analisi interattiva nel browser (esempio), utilizzando grafici a barre \u201cFlameGraph\u201d e mappe \u201cFlameScope\u201d con evidenziazione a colori dei punti critici. I grafici sono interattivi e consentono di ingrandire il dettaglio fino ai frame dello stack e alle istruzioni eseguite dalla GPU, visualizzando dettagli e effettuando operazioni di ricerca.
