A Japanese research group was awarded the ACM Gordon Bell Prize, Peak-Performance at SC11, the International Conference for High Performance Computing, Networking, Storage and Analysis, in Seattle on Nov. 17.
The scientists from RIKEN, the University of Tsukuba, the University of Tokyo and Fujitsu Ltd. obtained their research results using a "K computer," to reveal the electron states of silicon nanowires, which have attracted attention as a core material for next-generation semiconductors.
To verify the computational performance of the K computer, quantum-mechanical computations were performed on the electron states of a nanowire with approximately 100,000 atoms.
The results of the detailed calculations on the electron states of silicon nanowires, comprised of 10,000 to 40,000 atoms, clarified that electron transport characteristics will change depending on the cross-sectional shape of the nanowire.
The award marked the first time that a research group from Japan has won the Gordon Bell Prize for Peak-Performance since 2004.
