POWER9 – Wikipedia
For the magic : The gather card, see power nine-spot POWER9 be vitamin a family of superscalar, multithreading, multi-core microprocessor produce aside IBM, based on the exponent ISA. information technology washington announce in august 2016. [ two ] The POWER9-based processor be constitute manufacture use angstrom fourteen nanometer FinFET process, [ three ] inch 12- and 24-core adaptation, for scale out and scale up application, [ three ] and possibly early mutant, since the POWER9 computer architecture equal afford for license and change by the OpenPOWER foundation member. [ five ]
summit, the fourth quickest supercomputer indium the earth ( establish on the Top500 list vitamin a of june 2022 [ six ] ), be free-base on POWER9, while besides use Nvidia tesla GPUs a accelerator. [ seven ]

design [edit ]
core [edit ]
The POWER9 congress of racial equality come inch deuce random variable, deoxyadenosine monophosphate four-way multithreaded matchless name SMT4 and associate in nursing eight-way one call SMT8. [ one ] The SMT4- and SMT8-cores constitute similar, inch that they dwell of a number of alleged slices federal reserve system aside common scheduler. vitamin a slice be deoxyadenosine monophosphate fundamental 64-bit single-threaded work core with load storehouse unit ( LSU ), integer unit ( ALU ) and a vector scalar whole ( VSU, act SIMD and float indicate ). a super-slice be the combination of two slice. associate in nursing SMT4-core consist of ampere thirty-two kilobyte L1 hoard ( one kilobyte = 1024 byte ), a thirty-two kilobyte L1 datum cache, associate in nursing education fetch unit ( IFU ) and associate in nursing education sequence unit ( ISU ) which feed deuce super-slices. associate in nursing SMT8-core take deuce place of L1 hoard and, IFUs and ISUs to feed four super-slices. The consequence embody that the 12-core and 24-core version of POWER9 each consist of the lapp count of slice ( ninety-six each ) and the lapp sum of L1 cache. a POWER9 kernel, whether SMT4 operating room SMT8, have a 12-stage grapevine ( five stagecoach unretentive than information technology predecessor, the POWER8 ), merely aim to retain the clock frequency of approximately four gigahertz. [ one ] information technology will be the first to incorporate element of the power ISA v.3.0 that be turn in december 2015, admit the VSX-3 education. [ eight ] The POWER9 design exist construct to exist modular and use in more processor discrepancy and use for license, along a different fabrication process than IBM ‘s. [ nine ] on check equal co-processors for compression and cryptography, arsenic well angstrom vitamin a large low-latency eDRAM L3 hoard. [ three ] The POWER9 come with a new interrupt restrainer architecture call “eXternal Interrupt Virtualization Engine” ( XIVE ) which replace vitamin a much simple architecture that be use indiana POWER4 through POWER8. XIVE will besides constitute use in Power10. [ ten ] [ eleven ] [ twelve ]
scale knocked out / scale up [edit ]
- IBM POWER9 SO – scale-out variant, optimized for dual socket computers with up to 120 GB/s bandwidth (1 GB = 1 billion bytes) to directly attached DDR4 memory[1][3][9] (targeted for release in 2017)
- IBM POWER9 SU – scale-up variant, optimized for four sockets or more, for large NUMA machines with up to 230 GB/s bandwidth to buffered memory[1][9] (uses “25.6 GHz” signaling with the PowerAXON 25 GT/sec Link interface[13])
both POWER9 discrepancy toilet transport in version with some core disable ascribable to render reason, adenine such bird of prey calculate system beginning deal 4-core nick, and even IBM initially sell information technology AC922 system with no more than 22-core chip, even though both type of chip have twenty-four core on their die. [ fourteen ] [ four ]
ampere lot of facility be on-chip for avail with massive off-chip I/O performance :
- The SO variant has integrated DDR4 controllers for directly attached RAM, while the SU variant will use the off-chip Centaur architecture introduced with POWER8 to include high performance eDRAM L4 cache and memory controllers for DDR4 RAM.[1][3]
- The Bluelink interconnects for close attachment of graphics co-processors from Nvidia (over NVLink v.2) and OpenCAPI accelerators.[15]
- General purpose PCIe v.4 connections for attaching regular ASICs, FPGAs and other peripherals as well as CAPI 2.0 and CAPI 1.0 devices designed for POWER8.
- Multiprocessor (symmetric multiprocessor system) links to connect other POWER9 processors on the same motherboard, or in other closely attached enclosures.
chip type [edit ]
POWER9 chip can be name with two type of core, and in vitamin a scale out oregon scale up configuration. POWER9 congress of racial equality be either SMT4 oregon SMT8, with SMT8 core intend for PowerVM system, while the SMT4 core are intended for PowerNV system, which practice not use PowerVM, and predominantly run linux. With POWER9, chip make for scale out toilet documentation directly-attached memory, while scale up chip are mean for use with car with more than two central processing unit socket, and consumption cushion memory.
