KEK Supercomputer System

 

High Energy Accelerator Research Organization (KEK) is running the supercomputer system.

 

The next supercomputer system is composed of two main computation servers, System-A: Hitachi SR16000 model M1 and System-B: IBM Blue Gene/Q.

The System-A is now in service since 1 March 2012 at KEK, after test run period from 1 Sep 2011 to 31 Jan 2012 at the data center. The system-B started service at 1 April 2012.

 

System-A

The computation server of System-A is Hitachi supertechnical server SR16000 model M1 (15 Jul 2011 news release) and has the following specification.

 

♦ Total peak performance: 54.9 TFlops

♦ Total main memory: 14 TB

♦ Number of nodes: 56

♦ Peak performance per node: 980.48 GFlops

♦ Main memory per node: 256 GB

♦ Number od cores per node: 32

♦ Processor: POWER7 3.83GHz

♦ Disk storage: 546 TB

 

System-A is suitable to a shared momory parallel computation on single node, as well as an inter-node parallel computation with message passing. For parallel computation on cores of a node, automatic parallelizing compiler is available. This machine enables high performance computing in wide range of science.

 

System-B

The computation server of System-B is IBM Blue Gene/Q. and has the following specification.

 

♦ Number of racks: 6 (3 racks will start from October 2012)

♦ Total peak performance: 1.2558PFlops

♦ Total main memory: 96 TB

♦ Specification per rack: 209.7 TFlops, 16 TB memory

♦ Number of nodes per rack: 1024

♦ Specification per node: 204.8 GFlops, 16 GB memory

♦ 5-dimensional torus network

 

System-B has fast inter-node communication devices and composed of the architecture suitable to massively parallel computation.

 

KEK supercomputer system can be used in collaborated researches concerning KEK projects and research projects in elementary particle and nuclear physics including related fields. Details of application will be announced in the site of KEK Large Scale Simulation Program.
