IBM a annonc\u00e9<\/a><\/noindex> sur la transformation de l'architecture de l'ensemble d'instructions (ISA) Power en une version ouverte. En 2013, IBM a d\u00e9j\u00e0 fond\u00e9 le consortium OpenPOWER, permettant ainsi la licence de la propri\u00e9t\u00e9 intellectuelle li\u00e9e \u00e0 POWER et offrant un acc\u00e8s complet aux sp\u00e9cifications. Cependant, des redevances \u00e9taient toujours per\u00e7ues pour l'obtention d'une licence de fabrication de puces. \u00c0 partir de maintenant, la cr\u00e9ation de modifications des puces bas\u00e9es sur l'architecture d'ensemble d'instructions Power sera accessible au public et ne n\u00e9cessitera pas de redevances. De plus, le droit d'utiliser gratuitement tous les brevets associ\u00e9s \u00e0 Power d'IBM est accord\u00e9, et la gestion du projet est transf\u00e9r\u00e9e \u00e0 la communaut\u00e9, qui d\u00e9sormais
\nsera impliqu\u00e9e dans les processus de prise de d\u00e9cision.<\/p>\n

L'organisation en charge du d\u00e9veloppement, OpenPOWER Foundation, sera traduit<\/a><\/noindex> plac\u00e9e sous l'\u00e9gide de la Linux Foundation, ce qui permettra de cr\u00e9er une plateforme ind\u00e9pendante pour le d\u00e9veloppement conjoint de l'architecture Power, sans lien avec un fabricant sp\u00e9cifique. Le consortium OpenPOWER a d\u00e9j\u00e0 accueilli<\/a><\/noindex> plus de 350 entreprises. Plus de 3 millions de lignes de code de firmwares, de sp\u00e9cifications et de sch\u00e9mas n\u00e9cessaires \u00e0 la cr\u00e9ation de puces compatibles avec Power ont \u00e9t\u00e9 transmis \u00e0 la communaut\u00e9. <\/p>\n

En plus de la transformation en composantes Open Hardware de l'architecture de l'ensemble d'instructions, IBM a \u00e9galement transmis \u00e0 la communaut\u00e9 certaines technologies connexes utilis\u00e9es dans les puces Power9, y compris l'impl\u00e9mentation logicielle (softcore) de l'ISA POWER, ainsi que le design de r\u00e9f\u00e9rence pour le d\u00e9veloppement d'extensions bas\u00e9es sur les interfaces OpenCAPI<\/a><\/noindex> (Open Coherent Accelerator Processor Interface) et OMI (Open Memory Interface). L'impl\u00e9mentation logicielle fournie permet de simuler le fonctionnement d'un processeur de r\u00e9f\u00e9rence en utilisant les FPGA Xilinx. <\/p>\n

La technologie OpenCAPI permettra d'atteindre une performance maximale et d'\u00e9liminer les goulets d'\u00e9tranglement lors de l'interaction entre les c\u0153urs de processeur et les dispositifs int\u00e9gr\u00e9s, tels que les GPU, ASIC, divers acc\u00e9l\u00e9rateurs mat\u00e9riels, puces r\u00e9seau et contr\u00f4leurs de stockage de donn\u00e9es. L'OMI permettra d'acc\u00e9l\u00e9rer la bande passante des contr\u00f4leurs de m\u00e9moire et de r\u00e9duire les latences. Par exemple, gr\u00e2ce \u00e0 ces ajouts bas\u00e9s sur Power, il sera possible de cr\u00e9er des puces sp\u00e9cialis\u00e9es optimis\u00e9es pour r\u00e9soudre les probl\u00e8mes d'intelligence artificielle et d'analyse de donn\u00e9es haute performance en m\u00e9moire. <\/p>\n

Compar\u00e9 aux architectures ouvertes d\u00e9j\u00e0 disponibles MIPS<\/a><\/noindex> et RISC-V<\/a><\/noindex>, l'architecture Power est surtout attrayante pour sa capacit\u00e9 \u00e0 cr\u00e9er des syst\u00e8mes serveur modernes, des plateformes industrielles et des clusters. Par exemple, en collaboration avec IBM, NVIDIA et Mellanox ont lanc\u00e9 deux des plus grands clusters au monde bas\u00e9s sur l'architecture Power, menant de la libert\u00e9 sur Internet illustre clairement cette d\u00e9pendance : dans les pays o\u00f9 les droits de l'homme sont viol\u00e9s, les gouvernements bloquent les ressources \u00ab ind\u00e9sirables \u00bb ou restreignent l'acc\u00e8s au r\u00e9seau mondial.<\/a><\/noindex> le classement des supercalculateurs Top500.<\/p>\n
