An\u00fancio do processador Cerebras \u2015 Cerebras Wafer Scale Engine (WSE) ou motor Cerebras de escala de wafer \u2015 ocorreu<\/a><\/noindex> Durante a confer\u00eancia anual Hot Chips 31. O que surpreende n\u00e3o \u00e9 apenas o fato de terem conseguido produzir este monstro de sil\u00edcio. O que impressiona \u00e9 a aud\u00e1cia da ideia e o trabalho dos desenvolvedores, que se arriscaram a criar um cristal com uma \u00e1rea de 46.225 mil\u00edmetros quadrados e lados de 21,5 cm. Para fabricar um \u00fanico processador, \u00e9 necess\u00e1rio uma chapa de 300 mm. Com o menor erro, a taxa de rejei\u00e7\u00e3o atinge 100%, e o custo \u00e9 dif\u00edcil de imaginar.<\/p>\n

\"Cerebras<\/p>\n

A produ\u00e7\u00e3o do Cerebras WSE \u00e9 realizada pela empresa TSMC. O processo tecnol\u00f3gico \u00e9 de 16 nm FinFET. Este fabricante taiwan\u00eas tamb\u00e9m merece um monumento pela produ\u00e7\u00e3o do Cerebras. A fabrica\u00e7\u00e3o de um chip desse tipo exigiu maestria suprema e a solu\u00e7\u00e3o de uma s\u00e9rie de problemas, mas valeu a pena, afirmam os desenvolvedores. O chip Cerebras \u00e9, na pr\u00e1tica, um supercomputador em um chip, com uma incr\u00edvel largura de banda, consumo m\u00ednimo e parallelismo fant\u00e1stico. Atualmente, \u00e9 a solu\u00e7\u00e3o ideal para aprendizado de m\u00e1quina, permitindo que os pesquisadores comecem a resolver problemas de complexidade excepcional.<\/p>\n

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

Cada cristal Cerebras WSE cont\u00e9m 1,2 trilh\u00f5es de transistores organizados em 400.000 n\u00facleos de computa\u00e7\u00e3o otimizados para IA e 18 GB de mem\u00f3ria SRAM distribu\u00edda local. Tudo isso est\u00e1 conectado em uma malha com um desempenho total de 100 petabits por segundo. A largura de banda da mem\u00f3ria atinge 9 PB\/s. A hierarquia da mem\u00f3ria \u00e9 de n\u00edvel \u00fanico. N\u00e3o h\u00e1 cache, n\u00e3o h\u00e1 sobreposi\u00e7\u00f5es, e as lat\u00eancias de acesso s\u00e3o m\u00ednimas. Essa \u00e9 a arquitetura ideal para acelerar tarefas relacionadas \u00e0 IA. N\u00fameros brutos: em compara\u00e7\u00e3o com os n\u00facleos gr\u00e1ficos mais modernos, o chip Cerebras oferece 3.000 vezes mais mem\u00f3ria no chip e 10.000 vezes maior velocidade de troca com a mem\u00f3ria.<\/p>\n

\"Cerebras<\/p>\n

Os n\u00facleos computacionais Cerebras \u2014 SLAC (Cores de \u00c1lgebra Linear Espessa) \u2014 s\u00e3o totalmente program\u00e1veis e podem ser otimizados para trabalhar com qualquer tipo de rede neural. Al\u00e9m disso, a arquitetura dos n\u00facleos filtra os dados representados por zeros desde o in\u00edcio. Isso libera recursos computacionais da necessidade de realizar opera\u00e7\u00f5es de multiplica\u00e7\u00e3o a zero, o que significa, para cargas com dados esparsos, acelera\u00e7\u00e3o dos c\u00e1lculos e grande efici\u00eancia energ\u00e9tica. Dessa forma, o processador Cerebras se mostra centenas ou at\u00e9 milhares de vezes mais eficiente para aprendizado de m\u00e1quina em termos de \u00e1rea de cristal utilizada e consumo de energia do que as solu\u00e7\u00f5es atuais para IA e aprendizado de m\u00e1quina.<\/p>\n

\"Cerebras<\/p>\n

A fabrica\u00e7\u00e3o de um chip desse tamanho exigiu<\/a><\/noindex> uma s\u00e9rie de solu\u00e7\u00f5es \u00fanicas. Sua embalagem teve que ser feita quase manualmente. Houve problemas com a alimenta\u00e7\u00e3o el\u00e9trica do cristal e seu resfriamento. A dissipa\u00e7\u00e3o de calor s\u00f3 foi poss\u00edvel atrav\u00e9s de l\u00edquido e com a organiza\u00e7\u00e3o de um fornecimento zonal com circula\u00e7\u00e3o vertical. No entanto, todos os problemas foram resolvidos, e o chip saiu funcional. Ser\u00e1 interessante conhecer sua aplica\u00e7\u00e3o pr\u00e1tica.<\/p>\n
