Cette m\u00e9moire serait donc capable de r\u00e9aliser elle-m\u00eame certains calculs qui incombent traditionnellement aux CPU, GPU ou autres FPGA ; il est question d\u2019une puissance de 1,2 TFLOPS FP16. L\u2019architecture permettrait de doubler les performances par rapport \u00e0 un syst\u00e8me avec de la m\u00e9moire HBM &#8220;classique&#8221; et de r\u00e9duire la consommation

<em>bank<\/em> embarque une PCU (<em>Programmable Computing Unit Block<\/em>) cadenc\u00e9e \u00e0 300 MHz : en tout, il y a 32 PCU par puce. Naturellement, ces PCU prennent de la place : elles r\u00e9duisent la capacit\u00e9 de moiti\u00e9 (4 Gb au lieu de 8 Gb pour de la m\u00e9moire HBM2 sans PCU). Samsung rem\u00e9die partiellement \u00e0 ce probl\u00e8me en combinant quatre puces avec PCU de 4 Gb et quatre puces sans PCU de 8 Gb, pour une capacit\u00e9 totale de 6 Go. Au passage, vous avez s\u00fbrement constat\u00e9 que la documentation technique fait r\u00e9f\u00e9rence \u00e0 une technologie FIMDRAM (<em>Function-In Memory DRAM<\/em>) ; il s\u2019agit de l\u2019appellation interne, le nom final pour cette m\u00e9moire est bien HMB-PIM.<\/p>\n\n\n\n<p class=\"has-background has-very-light-gray-background-color\"><strong>SK Hynix pr\u00e9sente sa m\u00e9moire HBM2E, plus rapide que celle de Samsung<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">\u00c9viter des transferts de donn\u00e9es inutiles<\/h2>\n\n\n\n<p>L\u2019id\u00e9e qui sous-tend cette architecture est la suivante : \u00e9viter le transfert de donn\u00e9es entre la m\u00e9moire et le processeur, co\u00fbteux en \u00e9nergie et en temps. Ainsi, int\u00e9grer des PCU directement au sein de la m\u00e9moire supprime ces trajets ; cela fait gagner du temps, diminue la consommation et donc la chaleur g\u00e9n\u00e9r\u00e9e. Un attribut d\u00e9cisif pour les puces HBM, souvent empil\u00e9es les unes sur les autres au sein de syst\u00e8mes dont le refroidissement n\u2019est pas chose ais\u00e9e.<\/p>\n\n\n\n<p>Par ailleurs, Samsung indique que cette m\u00e9moire HMB-PIM ne <em>&#8220;n\u00e9cessite aucune modification des contr\u00f4leurs de m\u00e9moire conventionnels et de leurs protocoles de commande, ce qui rend la FIMDRAM id\u00e9ale pour une adoption rapide par l&#8217;industrie&#8221;.<\/em><\/p>\n\n\n\n<p>La m\u00e9moire HMB-PIM est actuellement en phase de tests dans des acc\u00e9l\u00e9rateurs IA. Toutes les validations seront faites d\u2019ici la fin du premier semestre 2021. Cependant, n\u2019esp\u00e9rez pas la voir d\u00e9barquer dans nos cartes graphiques rapidement : elle sera destin\u00e9e aux secteurs du HPC, des centres de donn\u00e9es et des applications mobiles IA dans un premier temps.<\/p>\n\n\n\n<p>Kwangil Park, vice-pr\u00e9sident senior de la planification des produits de m\u00e9moire chez Samsung Electronics, d\u00e9clare : <em>&#8220;Notre HBM-PIM r\u00e9volutionnaire est la premi\u00e8re solution PIM programmable de l&#8217;industrie adapt\u00e9e aux diverses charges de travail li\u00e9es \u00e0 l&#8217;IA telles que le HPC, la formation et l&#8217;inf\u00e9rence. Nous pr\u00e9voyons de tirer parti de cette avanc\u00e9e en collaborant davantage avec les fournisseurs de solutions d&#8217;IA pour des applications PIM encore plus
