One approach of new parallel architecture for real space descritization methods

Kushida, Noriyuki

In this presentation, a new approach of new computer architecture specialized for real space descritization method was presented. To achieve the speed up of scientific supercomputer, there are roughly two ways; (1) Accelerate processing speed of each unit (2)Increase the number of precessing unit. Currently, we are reaching the bound of both ways, however, I could point out thatone can extremely reduce the amount of communication when the algorithm is specialized to real space descritization method. In line with this context, memory connected parallel architecture was introduced and I could present that principal numerical operation could be operated on such architecture.
