#1 on the Green500 - Supermicro and Preferred Networks (PFN) Collaborate to Develop the World's Most Efficient Supercomputer

Deep Learning Supercomputer MN-3 Achieves Record 21.11 Gigaflops Performance-Per-Watt Based on Real-World Scientific Application Benchmarks

San Jose, Calif., August 31, 2020 -- Super Micro Computer, Inc. (Nasdaq: SMCI), a global leader in enterprise computing, storage, networking solutions and green computing technology, today announced that its collaboration with Preferred Networks achieved the #1 ranking for the Green500 semi-annual industry assessment. The MN-3 reached a record 21.11 Gigaflops of performance-per-watt on a benchmark run that delivered a total performance of 1.62 Petaflops. This efficiency achievement is 15% higher than the previous Green500 record of 18.404 Gflops/W, which was recorded in June 2018.

"Supermicro was excited to work with PFN on this exceptional system supporting machine learning (ML) and deep learning (DL) applications and energy efficiency," said Charles Liang, CEO and president of Supermicro. "The Green500 international recognition confirms that Supermicro delivers exceptional products – resource-saving, superior design, and high-reliability to the market."

PFN partnered with Supermicro to develop this customized server, which addresses a wide range of applications that require ultra-fast communications. Based in Japan, PFN strives to solve complex problems that utilize deep learning, robotics, and other advanced technologies.

"We are very pleased to have partnered with Supermicro, who worked with us very closely to build MN-3, which was recognized as the world's most energy-efficiency supercomputer"., stated Yusuke Doi, VP of Computing Infrastructure at Preferred Networks. "We can deliver outstanding performance while using a fraction of the power that was previously required for such a large supercomputer."

The PFN solution is based on the Supermicro GPU server that utilizes Intel® Xeon® CPUs, and MN-Core™ boards developed by Preferred Networks. This advanced system offers up to 6TB of DDR4 memory, and multiple GPUs or accelerators, as well as the interconnects that enable ultra-fast communications between GPUs.
