Innovators embrace new ideas to create or do things that challenge the status quo. But why do they take these risks? What triggers their inspiration? Hear from the experts who've actualized their ambitions.
A Completely Submerged "Chilled Server!?"–A Novel Idea Good for Both the Global Environment and the ICT Society (Part 1)
In the ICT society, the number of Internet-connected devices and sensors continues to grow astronomically. Handling the huge amount of heat generated by data centers and IT devices is an urgent issue to ensure stable system operation as well as the health of the global environment. Fujitsu has developed a novel liquid immersion cooling system that cools down servers by completely immersing them in liquid. This system won the 2018 Energy Conservation Grand Prize (for the first time) and the Environment Minister's Award for Global Warming Prevention Activity (second year in a row, sixth time overall). For this article, we interviewed Takashi Yamamoto, leader of the R&D project, about the process for commercializing this technology and its future potential.

Extreme weather events are reported all over the world. The need for technologies to help prevent global warming continues to rise. The liquid immersion cooling system developed by Yamamoto’s team reduces the entire server system’s power consumption by nearly 40% compared to those with conventional air cooling systems. Because it can easily demonstrate effects even in severe environments, people worldwide are paying close attention to the system.
Customer Engineers’ Attempt to Keep the World’s Oldest Computer Running (Part 1)
One of the world’s oldest computers, FACOM128B relay computer made in 1959, is still operational in Fujitsu’s Numazu Complex. Customer Engineers (CEs) have kept it running for 60 years, an unprecedentedly long maintenance period. CEs are the ones to support today’s ICT systems, on one hand, maintains the world’s oldest computer to keep running. What is the meaning of it? What is their mission? We interviewed Nobuyuki Hori, the CE group leader, and Tadao Hamada, the advocate for running FACOM128B.
Customer Engineers’ Attempt to Keep the World’s Oldest Computer Running (Part 2)
(Continued from Part 1 of the interview.) The social infrastructure that supports our lives has evolved alongside technology and become indispensable. Today, any system trouble may make our lives dysfunctional. Such risks must be predicted, prevented, and eliminated quickly. As the keepers of such systems, CEs face major changes.
Building the Ultimate Supercomputer with 8,000+ General-Purpose Servers! Large-Scale PC Cluster Configuration Technology (Part 1)
Today's mainstream supercomputers are "PC clusters"—in other words, a multitude of PC servers equipped with general-purpose CPUs that are connected together to form a cluster. As the cluster scale increases, the speed and stability of each PC (node) and the network that connects an enormous number of nodes become problematic. A Fujitsu research team tackled this problem to develop Oakforest-PACS, a supercomputer jointly introduced by the University of Tokyo and the University of Tsukuba that successfully demonstrated globally top-tier performance. In recognition of this large-scale PC cluster configuration technology, the team received the prize for Science and Technology from Japan's Minister of Education, Culture, Sports, Science, and Technology in April 2018. In this interview, Kohta Nakashima talks about what went on behind the scenes to make the impossible possible as well as his passion for research.

(Continued from Part 1.) In the Oakforest-PACS project, Nakashima's research and development group gained confidence about their large-scale PC cluster configuration technology by recording better performance than rival teams from other countries with big budgets. To Nakashima, what is a team that creates innovations?
Contributing to Medicine and Society with Heart Simulator Technology (Part 2)
(Continued from Part 1 of the interview.) In April 2018, three co-researchers including Masahiro Watanabe were awarded a prize in the Research Category for Science and Technology at the Commendation for Science and Technology from the Minister of Education, Culture, Sports, Science and Technology (MEXT) for "Clinical research using a heart simulator." The heart simulator R&D project, which was launched with University of Tokyo in 2008, is now beginning to be used in the real world in fields such as medical education.
Contributing to Medicine and Society with Heart Simulator Technology (Part 1)
The more we attempt to solve the mysteries of the human body and life, the more we learn of their wonders and preciousness. While the heart is one of the most difficult organs to understand, R&D on the "Heart Simulator," which simulates and visualizes the heart's complex movements on a computer, is underway. We interviewed Masahiro Watanabe, Heart Simulator R&D Leader at Fujitsu, about the history of this revolutionary technological development and innovations that contribute to medicine and society.
