Ppc64le
ppc64 is an identifier commonly used within the Linux, GNU Compiler Collection (GCC) and LLVM free software communities to refer to the target architecture for applications optimized for 64-bit big-endian PowerPC and Power ISA processors. ppc64le is a pure little-endian mode that has been introduced with the POWER8 as the prime target for technologies provided by the OpenPOWER Foundation, aiming at enabling porting of the x86 Linux-based software with minimal effort. Details These two identifiers are frequently used when compiling source code to identify the target architecture. 64-bit Power and PowerPC processors are the following: * PowerPC 620 * RS64 – Apache, RS64-II Northstar, RS64-III Pulsar/IStar, and RS64-IV SStar * POWER3 and POWER3-II * POWER4 and POWER4+ * PowerPC 970, 970FX, 970MP and 970GX * POWER5 and POWER5+ * PPE in Cell BE, PowerXCell 8i and Xenon. * PWRficient * POWER6 and POWER6+ * POWER7 and POWER7+ * A2, A2I (used in the Blue Gene/Q) a ...

POWER9
POWER9 is a family of superscalar, multithreading, multi-core microprocessors produced by IBM, based on the Power ISA. It was announced in August 2016. The POWER9-based processors are being manufactured using a 14 nm FinFET process, in 12- and 24-core versions, for scale out and scale up applications, and possibly other variations, since the POWER9 architecture is open for licensing and modification by the OpenPOWER Foundation members. Summit, the ninth fastest supercomputer in the world (based on the Top500 list as of June 2024), is based on POWER9, while also using Nvidia Tesla GPUs as accelerators. Design Core The POWER9 core comes in two variants, a four-way multithreaded one called ''SMT4'' and an eight-way one called ''SMT8''. The SMT4- and SMT8-cores are similar, in that they consist of a number of so-called ''slices'' fed by common schedulers. A slice is a rudimentary 64-bit single-threaded processing core with load store unit (LSU), integer unit (ALU) and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Blue Gene/Q
Blue Gene was an IBM project aimed at designing supercomputers that can reach operating speeds in the petaFLOPS (PFLOPS) range, with relatively low power consumption. The project created three generations of supercomputers, Blue Gene/L, Blue Gene/P, and Blue Gene/Q. During their deployment, Blue Gene systems often led the TOP500 and Green500 rankings of the most powerful and most power-efficient supercomputers, respectively. Blue Gene systems have also consistently scored top positions in the Graph500 list. The project was awarded the 2009 National Medal of Technology and Innovation. After Blue Gene/Q, IBM focused its supercomputer efforts on the OpenPower platform, using accelerators such as FPGAs and GPUs to address the diminishing returns of Moore's law. History A video presentation of the history and technology of the Blue Gene project was given at the Supercomputing 2020 conference. In December 1999, IBM announced a US$100 million research initiative for a five-year ef ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

PWRficient
PWRficient is a microprocessor series by P.A. Semi where the PA6T-1682M was the only one that became an actual product. PWRficient processors comply with the 64-bit Power ISA, and are designed for high performance and extreme power efficiency. The processors are highly modular and can be combined to multi-core system-on-a-chip (SoC) designs, combining CPU, northbridge, and southbridge functionality on a single processor die.
