FUJITSU Supercomputer PRIMEHPC FX700

A high-performance Arm server featuring the A64FX CPU, the same CPU used in the supercomputer Fugaku.

Air-cooled and based on standard technology, making it easy to set up.

The FUJITSU Supercomputer PRIMEHPC FX700 is a

PRIMEHPC series air-cooled model based on

standard technology that features the A64FX CPU

for use in the supercomputer Fugaku developed

together with RIKEN and the PRIMEHPC FX1000. It is

the perfect system for customers that wish to easily

take advantage of the high performance of the

A64FX. It has a minimum hardware configuration of

2 nodes in Japan and 128 nodes overseas.

A64FX, the newly developed Arm CPU

The A64FX, developed by Fujitsu, is the world’s first

CPU to implement a Scalable Vector Extension

(SVE), an extension of the Armv8.2-A instruction set

architecture for supercomputers. Manufactured

using the state-of-the-art 7nm process, the A64FX

has 48 computing cores, can provide a theoretical

peak double-precision floating-point operations

performance of 2.7648 TFLOPS or 3.072 TFLOPS.

Furthermore, it is capable of high-throughput

single-precision/half-precision computation and

8bit/16bit integer operations using its 512-bit wide

SIMD units. This calculation performance shines in

processing applications such as AI.

Each node consists of one processor, and uses

HBM2 (High Bandwidth Memory 2), a world first for

a general-purpose CPU. Each node has a

tremendous 1,024 GB/s of memory bandwidth.

Microarchitecture with high processing

performance

The A64FX’s microarchitecture was developed using

technologies that Fujitsu has refined through its

experience with supercomputers, mainframes, and

UNIX servers. The A64FX carries on from the CMG

(Core Memory Group) of the PRIMEHPC series,

which enables scalable performance improvement

when using multiple cores, as well as VISIMPACT

(Virtual Single Processor by Integrated Multi-core

Parallel Architecture), which realizes highly efficient

hybrid parallel processing. It also enhances

functions such as SIMD functions.

Easy-deployment form factor and air cooled design

The PRIMEHPC FX700 has a 2U chassis that can be

mounted in standard 19-inch racks and can hold up

to four blades. Each blade contains two nodes, and

each unit can consist of up to eight nodes. It is air

cooled, making it easy to deploy high-performance

Arm servers in environments without specialized

water-cooling equipment.

Industry-standard interconnect and OS

The interconnect among compute nodes is the

industry-standard InfiniBand. InfiniBand is widely

used as an interconnect in PC clusters, and can be

used to construct equivalent topologies. The

FUJITSU Supercomputer PRIMEHPC FX700 uses the

Red Hat Enterprise Linux OS, offering a high level of

software migratability.

Development environment that leverages the

performance of the A64FX

Development environments such as compilers are

supplied by Fujitsu, providing powerful support for

the development and optimization of applications

for the A64FX CPU.

HPC software support

Bright Computing's Bright Cluster Manager, a

cluster management software, and Altair's Altair

PBS Professional, a job scheduler are supported.
