27th Workshop on Sustained Simulation Performance

About WSSP

Toward Future HPC Technologies

Cyberscience Center at Tohoku University, Japan Agency for Marine-Earth Science and Technology (JAMSTEC), High Performance Computing Center Stuttgart (HLRS), and NEC Corporation are pleased to announce that the 27th Workshop on Sustained Simulation Performance (WSSP) will be held on March 22nd and 23rd, 2018 in Sendai, Miyagi, Japan. The purpose of the workshop is to discuss future supercomputers, through the latest research efforts in large-scale computing with high performance and high efficiency.

We are looking forward to seeing you in the workshop.

About Cyberscience Center Award and 2017 Award Winner

As one of joint usage/research centers, it is important for the Cyberscience Center to research advanced usage technologies for exploiting the potential of large-scale scientific computing systems, develop the usage environments, and plan the next system installation based on the acquired knowledge. To smoothly accomplish those missions, it is mandatory for researchers in the Cyberscience Center to collaborate with researchers who practically use the large-scale computing system for their research fields.

The award-winner, Professor Toshiki Iwasaki, has been continuously conducting joint research with the Cyberscience Center, developing advanced simulation technologies, and producing many results regarding advanced usage technologies. Moreover, the knowledge obtained by his work has significantly contributed to the design and advancement of large-scale scientific computing systems in the Cyberscience Center. He made significant contributions also as the specification committee chair for discussing the system specifications installed at the Cyberscience Center.

Keynote Presentations

In the workshop, four keynote talks are scheduled. The details are as followings.
