The 23rd Workshop on
Sustained Simulation Performance
March 16-17, 2016 / Sendai, Japan
Toward Future HPC Technologies
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 23rd Workshop on Sustained Simulation Performance (WSSP) will be held on March 16th and 17th, 2016 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.
In the workshop, two keynote talks are scheduled.
Abstract: The computing world is changing and all devices from mobile phones and personal computers to high-performance supercomputers are becoming parallel. At the same time, the efficient usage of all the opportunities offered by modern computing systems represents a global challenge. Using full potential of parallel computing systems and distributed computing resources requires new knowledge, skills and abilities, where one of the main roles belongs to understanding of key properties of parallel algorithms. What are these properties? What should be discovered and expressed explicitly in existing algorithms when a new parallel architecture appears? How to ensure efficient implementation of an algorithm on a particular parallel computing platform? All these as well as many other issues will be addressed in the talk.
The idea that we use in educational practice at the university is to split a description of an algorithm into two parts. This helps us to explain what a good parallel algorithm is and what is important for its efficient implementation. The first part describes algorithms and their properties. The second part is dedicated to describing particular aspects of their implementation on various computing platforms. The first part draws attention to the key theoretical properties, and the second part puts emphasis on the aspects fundamentally important on practice. This division is made intentionally to highlight the machine-independent properties of algorithms which determine their potential and the quality of their implementations on parallel computing systems, and to describe them separately from a number of issues related to the subsequent stages of programming and executing the resulting programs. In addition to the classical algorithm properties such as serial complexity, we have to explain concepts such as parallel complexity, parallel structure, determinacy, data locality, performance and scalability estimates, communication profiles for specific implementations, and many others aspects.
This approach was successfully implemented as an open encyclopedia AlgoWiki, which is available for the computational community at www.AlgoWiki-Project.org.

Abstract: Numerical analyses were conducted to detect the time sequential deformation behaviors of diseased blood vessel wall with aneurysm under pulsatile pressure conditions using designed original program software based on computer fluid dynamics. To detect detailed these behaviors, it is necessary to conduct an analysis with high accuracy and long CPU time. We designed original algorithm to detect detailed behaviors of diseased blood vessel wall with aneurysm, however it takes much CPU time. Using super computer, CPU time of the numerical analysis was also successfully shortened and it will enable us to apply this analysis to actual blood vessel structure.
