Computational Science Research Program, RIKEN
The Next-Generation Integrated Simulation of Living Matter (ISLiM) program held an Interim Accomplishment Meeting in 2011 at Takeda Hall in the University of Tokyo on December 21 (Wed) and 22 (Thu), 2011.
ISLiM program was launched in October 2006 along with the development of the K computer, with the aim to understand life phenomena more deeply and to contribute to drug discovery and healthcare in particular. It remains one year to go before completion of this program. The researchers of 14 universities and institutes have been making collaborative efforts to develop ISLiM software and optimize them for the K computer. ISLIM develops 33 homegrown application programs, and challenges the most efficient, large-scale, and highly accurate simulation with K computer. A total of 141 researchers specializing in life sciences and healthcare from industry and academia attended the ISLiM Interim Accomplishment Meeting in 2011, where ISLiM software developers reported their latest results for two days.
First, Koji Kaya, Director of the Computational Science Research Program, gave an opening speech. Then, Ryutaro Himeno, Deputy Program Director of the program, explained the current status for development of application software, each of which has been optimized by using the K computer in trial operation from March or April 2011, and showed interim performance data. Himeno said, "Our efforts will be focused on optimization of ISLiM sof t ware until November 2012 when K computer becomes generally available. The performances for some software products (cppmd, ZZ-EFSI) have reached to 20-30% of the peak performance of the K computer. Further efforts will be directed to improvement of performance and to dissemination of the software."
Afterwards, the leaders of the six ISLiM teams (Molecular Scale Team, Cell Scale Team, Organ and Body Scale Team, Data Analysis Fusion Team, Brain and Neural Systems Team, and High-performance Computing Team) and ISLiM's researchers in charge of development of ISLiM software reported their latest achievements. The details of their reports (mostly in Japanese) can be downloaded from the website of ISLiM (URL: http://www.csrp.riken. jp/2011/islim-houkokukai2011_j.html).
Because two days are too short to present all the ISLiM developed software in depth, four-poster sessions were held in the foyer at Takeda Hall. A total of 38 posters were exhibited there, and the software developers gave explanations to audiences from industry, etc. Some of them had deep discussions in front of the posters.
Participants from industry appreciated the presentations in the meeting, saying that they understood how widely and deeply ISLiM researchers were involved in research and development of ISLiM software, even in vivo study. But, such comments suggest that ISLiM software has been little recognized by people in our target area outside the project. Then, we will organize an ISLiM Accomplish Meeting in the fall of 2012, and foster programs that can improve visibility of ISLiM software as well as dissemination.
The performance data with the K computer are obtained through the experimental use since April 2011 or its special operation in March 2011 before general availability in November 2012.
