Red Hat on supercomputers. 4 of the 10 most powerful use it

Red Hat on supercomputers

Red Hat, Inc. announced that su Red Hat Enterprise Linux product is the operating system foundation for the world's top three supercomputers and four of the top 10 in the 500 list that make up the ranking.

Red Hat on supercomputers. The 4 that use Red Hat Enterprise Linux

In the top ten positions on the current TOP500 list, Red Hat Enterprise Linux serves as the operating system for:

  • Fugaku, the supercomputer that tops the ranking and is located at the RIKEN Center for Computational Sciences in Kobe, Japan.
  • Summit, the second-place supercomputer, is located at the Oak Ridge National Laboratory in Oak Ridge, Tennessee.
  • Sierra, which ranks third, is used at the Lawrence Livermore National Laboratory in Livermore, California.
  • Marconi-100, ranked ninth, is based at the CINECA research center in Italy.

Fugaku

Fugaku is eThe first ARM processor-based system to rank first on the TOP500 list. Its development began in 2014 and it is expected to reach full operation in 2021.

The supercomputer eIt is built with the Fujitsu A64FX microprocessor. This CPU is based on the ARM version 8.2A processor architecture, and adopts Scalable Vector Extensions for supercomputers. Fugaku expects a performance target of 1 exaFLOP for which it will use 158.976 A64FX CPUs linked together using proprietary interconnect technology developed by Fujitsu.

Fugaku It runs a lightweight multi-core operating system called IHK / McKernel. The operating system uses both Linux and the lightweight McKernel kernel operating simultaneously and side by side. The infrastructure on which both kernels operate is called Interface for Heterogeneous Cores (IHK)

McKernel is used for high-performance simulations, leaving Linux to take care of all other POSIX-compliant services.

Summit

Summit, Sierra and Marconi-100 have an infrastructure based on IBM POWER9 with NVIDIA GPUs; Combined, these four systems produce more than 680 petaflops of processing power to power a wide range of scientific research applications.

Summit was developed by IBM and has a capacity of 200 petaFLOPS. It is the first supercomputer to achieve the speed of exaflop (quintillion operations per second), lograding 1,88 exaflops during a genomic analysis and is expected to reach 3,3 exaflops using mixed precision calculations.

Che operating system uses Red Hat Enterprise Linux and its hardware is made up of 216 POWER9 22-core CPUs and 27,648 Nvidia Tesla V100 GPUs.  POWER9 CPUs and Volta GPUs are connected using Nvidia's high-speed NVLink.

Sierra

Sierra it is very similar in design to the Summit supercomputer discussed above. Sierra system uses IBM POWER9 CPUs in conjunction with Nvidia Tesla V100 GPUs. Sierra nodes are Witherspoon S922LC OpenPOWER servers with two GPUs per CPU and four GPUs per node. These nodes are connected to EDR InfiniBand. Its performance is 125 petaflops.

Marconi-100

The Marconi 100 is not too different either. a maximum throughput of around 32 Pflop / s, its internal network works with Mellanox Infiniband EDR DragonFly + technology. MARCONI100 It is based on the IBM Power9 architecture with NVIDIA Volta GPUs.

If you are a fan of the environment, those in the red hat also wear the green hat.

Red Hat Enterprise Linux is the Linux-based operating system for six of the 10 most energy-efficient supercomputers on the planet. In this case, both the performance and the energy consumed to achieve this are taken into account.

In the top ten on the list, Red Hat Enterprise Linux serves as the operating system for:

  • The A64FX prototype, (place number four) was created as the prototype system to test and develop the Fugaku supercomputer and is located at Fujitsu's plant in Numazu, Japan.
  • AIMOS (XNUMXth place) is at Rensselaer Polytechnic Institute in Troy, New York.
  • Satori (Ranked XNUMXth) is based at the MIT Massachusetts Green High Performance Computing Center (MGHPCC) in Holyoke, Massachusetts.

The eighth, ninth and tenth places are for the aforementioned Summit, Fugaku and Marconi-110
