Success establishing the 60 TFlops Supercomputer for fusion simulation research
-County’s third-performance Supercomputer, utilized for fusion plasma research-

□ The WCI (World Class Institute) Center for Fusion Theory directed by Prof. Patrick H. Diamond which is under the National Fusion Research Institute (President Gyung-su Lee) hosted a briefing about the completion of the high-performance cluster computer on the 29 ^th (Wed.) at 4pm. They briefed that establishment of the 60 TeraFlops level supercomputer for large- scale simulation research in the fusion plasma area has been finished and will begin full-scale operation.

○ The supercomputer is based on the HP blade system and evaluated as a low-power green supercomputing system. It reached that evaluation for the following reasons: (i) maximum theoretical performance is up to 60.8 TeraFlops, (ii) it has the highest performance as the Korean CPU socket registered in the world supercomputer TOP 500, and (iii) its high system has a integration capability with the capacity of having a install ation degree of 48 core per 5.5 cm.

○ This is Korea ’s third -ranked high- performance supercomputer following supercomputers from the Korea Meteorological Administration and the Korea Institute of Science and Technology Information (KISTI). Based on i ts performance and stability evaluation the supercomputer is ranked 423 place in the world Top 500.

□ The WCI Center for Fusion Theory conducts theoretical and simulation research of fusion plasma that is essential for commercialization of fusion energy. WCI is expected to fulfill the need to establish high - performance supercomputers which can simultaneously satisfy in two ways: a high-availability supercomputer for various simulation s and performance tests and efficient algorithm development of large-s ized codes that is needed to realize thousands of calculations simultaneously.

○ As of last November, WCI Center for Fusion Theory established the high-performance cluster supercomputer with LG N- S ys has been led by Jae-Min Kwon (Deputy director of WCI, R&D Division) . Achieving the final system established a new milestone and its success has led to the availability of large-capacity fusion simulation experiments through the effort of network performance increases and the new performance of the system stability test.

○ The new supercomputer will support massive large- scale simulation research of fusion plasmas. It will mostly be used for research in the WCI center aiming to ‘investigate fusion plasma turbulent transportation for predicting plasma performance of fusion devices more accurately’ under the leadership of Prof. Patrick H. Diamond. He was awarded recently the Hannes Alfvén Prize from the European Physical Society who is among the world’s highest authority within the plasma physics field.
