NAOJ Optimizes Supercomputer Power Consumption

Simulating Astronomy Calculations

Challenges
• Support research into numerical simulation by users in Japan and elsewhere
• Monitor and manage power consumption in the supercomputer
• Improve and optimize application and cluster performance

Solutions
• Install supercomputer cluster based on Intel® Xeon® processor E5 family
• Adopt Intel® Node Manager (Intel® NM) for power management
• Deploy Intel® Cluster Studio XE, a suite of tools for C++ and Fortran programmers and MPI application developers

Business Value
• Achieved real-time power monitoring and optimized power costs
• Improved simulation program development efficiency through the use of libraries
• Achieved 90 percent uptime with the supercomputer

Supporting Astronomical Researchers by Providing Shared Access to Supercomputer
The Center for Computational Astrophysics (CfCA) is a project of the National Astronomical Observatory of Japan (NAOJ), part of the National Institutes of Natural Sciences. It uses computer simulation to study the many mysteries of the universe. Its objective is to support simulation studies by researchers in Japan and elsewhere by operating computer systems on a joint access model. Among these systems are supercomputers, special-purpose computing machines for working on gravitational n-body problems, and small and medium-sized Intel® architecture-based clusters. To achieve its mission, the CfCA is currently working on new simulation techniques from both a hardware and software perspective.
