La compagnia IBM ha annunciato<\/a><\/noindex> ha convertito l'architettura dell'insieme di istruzioni (ISA) Power in un modello aperto. Nel 2013, IBM ha gi\u00e0 creato il consorzio OpenPOWER, attraverso il quale ha offerto la possibilit\u00e0 di licenziare la propriet\u00e0 intellettuale legata a POWER e ha fornito accesso completo alle specifiche. Tuttavia, le royalty per la licenza di produzione dei chip continuavano a essere raccolte. D'ora in poi, la creazione di proprie modifiche ai chip basati sull'architettura dell'insieme di istruzioni Power diventer\u00e0 accessibile a tutti e non richieder\u00e0 royalty. Viene inoltre concesso il diritto di utilizzare senza alcun costo tutti i brevetti relativi a Power di IBM, mentre la gestione del progetto sar\u00e0 trasferita alla comunit\u00e0, che ora
\nsar\u00e0 coinvolta nei processi decisionali.<\/p>\n

L'organizzazione che coordina lo sviluppo, OpenPOWER Foundation, sar\u00e0 tradotta<\/a><\/noindex> sotto l'egida della Linux Foundation, permettendo di creare una piattaforma indipendente per lo sviluppo collaborativo futuro dell'architettura Power, senza legami con un produttore specifico. Al consorzio OpenPOWER si sono gi\u00e0 uniti<\/a><\/noindex> oltre 350 aziende. Alla comunit\u00e0 sono stati forniti oltre 3 milioni di righe di codice, specifiche e schemi necessari per creare chip compatibili con Power. <\/p>\n

Oltre al trasferimento a componenti Open Hardware dell'architettura del set di istruzioni, IBM ha fornito alla comunit\u00e0 alcune tecnologie correlate utilizzate nei chip Power9, inclusa l'implementazione software (softcore) di POWER ISA, oltre a un design di riferimento per lo sviluppo di estensioni basate sulle interfacce OpenCAPI (Open Coherent Accelerator Processor Interface) e OMI (Open Memory Interface). L'implementazione software fornita consente di simulare il funzionamento di un processore di riferimento utilizzando FPGA Xilinx. OpenCAPI<\/a><\/noindex> (Open Coherent Accelerator Processor Interface) e OMI (Open Memory Interface). <\/p>\n

La tecnologia OpenCAPI permetter\u00e0 di ottenere prestazioni ottimali ed eliminare i colli di bottiglia nella comunicazione tra i nuclei di elaborazione e i dispositivi integrati, come GPU, ASIC, vari acceleratori hardware, chip di rete e controller di archiviazione. L'OMI aumenter\u00e0 la larghezza di banda dei controller di memoria e ridurr\u00e0 le latenza. Ad esempio, grazie a queste integrazioni basate su Power, sar\u00e0 possibile creare chip specializzati ottimizzati per le attivit\u00e0 di intelligenza artificiale e analisi ad alte prestazioni in memoria. <\/p>\n

Rispetto alle architetture aperte gi\u00e0 disponibili MIPS<\/a><\/noindex> e RISC-V<\/a><\/noindex>, l'architettura Power \u00e8 particolarmente interessante per la sua prontezza nella creazione di moderne sistemi server, piattaforme industriali e cluster. Ad esempio, in collaborazione tra IBM, NVIDIA e Mellanox, sono stati avviati due dei pi\u00f9 grandi cluster al mondo basati sull'architettura Power, che guidano la classifica<\/a><\/noindex> dei supercomputer Top500.<\/p>\n
