Ncku Develops World's First Switchless Cluster Supercomputer
TAINAN, Taiwan --(Business Wire)--
The National Cheng Kung University (NCKU) Supercomputing Research Center
(RSC) has built the world's first switchless cluster computer. Known as
the "CK-Star", this computer connects eight computers without switch
control, thus breaking Intel's (News - Alert) performance record.
Together with the computer systems provided by Acer, the CK-Star is
jointly built by NCKU RSC Director Dr. Chi-Chuan Hwang and Dr. Yuefan
Deng of Mainland China's National Supercomputing Center in Jinan
(NSCCJN), who is also a Distinguished Professor at the State University
of New York (SUNY).
NCKU RSC Director Dr. Chi-Chuan Hwang added that CK-Star is the most
unique switchless cluster supercomputer compared to traditional cluster
supercomputer which requires switch control to control interaction
He explaned that the weakness of the traditional one is that switches
will become performance bottlenecks when the number of nodes is large.
Besides, switches also consume large amount of power, estimated to be
50% of the total power consumption. With the introduction of the CK-Star
which allows the unrestricted expansion of supercomputers, these
problems can be overcome.
CK-Star also integrates the Intel® Xeon Phi™ coprocessor and has
produced record-breaking computer performance at 80.2% for four nodes
and 77.3% for eight nodes, beating Intel's previous world record of
79.6% for four nodes and 76.1% for eight nodes.
"CK-Star has an innovative structure and an enhanced performance. It has
overcome the limitations of switches and solved the problem of high
power dissipation through switches," Dr. Yuefan Deng explained.
In addition to CK-Star, the GS-R22PHL supercomputer, jointly built by
NCKU RSC and Gigabyte, has also been recorded to reach 3.7 teraflops
(3.7 trillion floating-point operations) in terms of computer
GS-R22PHL is currently the highest performing single supercomputer to
date, thus setting a world record in the field of supercomputers and a
new milestone in the history of computing.
The innovative skills were presented at Yue-sheng Lecture Hall of NCKU
Department of Engineering Science on November 18th and
attended by NCKU Vice President Chih-Chin Ho, NCKU Computer and Network
Center Director Jung-Hsien Chiang, and many other researchers and
