\"Cerebras<\/p>\n

La produzione del Cerebras WSE \u00e8 gestita da TSMC. Il processo tecnologico \u00e8 a 16 nm FinFET. Questo produttore taiwanese ha anche meritato un monumento per la realizzazione del Cerebras. La produzione di un chip di questo tipo ha richiesto abilit\u00e0 superiori e la risoluzione di una miriade di problemi, ma ne \u00e8 valsa la pena, affermano gli sviluppatori. Il chip Cerebras \u00e8 praticamente un supercomputer su un chip, con un'incredibile capacit\u00e0 di elaborazione, un consumo ridotto e un parallelismo fantastico. Attualmente \u00e8 la soluzione ideale per l'apprendimento automatico, permettendo ai ricercatori di affrontare compiti di straordinaria complessit\u00e0.<\/p>\n

\n<\/center><\/p>\n

Ogni cristallo di Cerebras WSE contiene 1,2 trilioni di transistor, organizzati in 400.000 unit\u00e0 di calcolo ottimizzate per l'IA e 18 GB di memoria SRAM distribuita locale. Tutto ci\u00f2 \u00e8 collegato tramite una rete a celle con una potenza complessiva di 100 petabit al secondo. La larghezza di banda della memoria raggiunge i 9 PB\/s. La gerarchia di memoria \u00e8 a livello singolo. Non ci sono cache, sovrapposizioni e i tempi di accesso sono minimi. Questa \u00e8 l'architettura ideale per accelerare i compiti legati all'IA. Numeri a confronto: rispetto ai pi\u00f9 avanzati nuclei grafici, il chip Cerebras offre 3000 volte pi\u00f9 memoria sul cristallo e una velocit\u00e0 di scambio con la memoria 10.000 volte superiore.<\/p>\n

\"Cerebras<\/p>\n

I nuclei di calcolo Cerebras \u2015 SLAC (Sparse Linear Algebra Cores) \u2015 sono completamente programmabili e possono essere ottimizzati per lavorare con qualsiasi rete neurale. Inoltre, l'architettura dei nuclei filtra inizialmente i dati rappresentati da zeri. Questo libera le risorse di calcolo dalla necessit\u00e0 di eseguire operazioni di moltiplicazione per zero, il che significa che per i carichi di dati sparsi si ottiene un'accelerazione nei calcoli e un'efficienza energetica senza precedenti. Pertanto, il processore Cerebras risulta essere centinaia o addirittura migliaia di volte pi\u00f9 efficace per l'apprendimento automatico in termini di superficie del cristallo utilizzata e consumo energetico, rispetto alle attuali soluzioni per IA e apprendimento automatico.<\/p>\n

\"Cerebras<\/p>\n

La produzione di un chip di tale dimensione ha richiesto<\/a><\/noindex> una quantit\u00e0 enorme di soluzioni uniche. \u00c8 stato persino necessario confezionarlo a mano. Sono emersi problemi con l'alimentazione del cristallo e il suo raffreddamento. L'espulsione del calore \u00e8 stata possibile solo grazie a un liquido e solo con l'organizzazione di un'adeguata alimentazione zonale con circolazione verticale. Tuttavia, tutti i problemi sono stati risolti e il chip \u00e8 entrato in produzione. Sar\u00e0 interessante scoprire il suo impiego pratico.<\/p>\n
