Software Technology that Deals with Deeper Memory Hierarchy in Post-petascale Era

■Outline of Research Theme

There is an urgent need to develop technology that realizes larger, finer and faster simulations in meteorology, bioinformatics, disaster measures and so on, towards post-petascale era. However, the "memory wall" problem will be the one of largest obstacles; the growth of memory bandwidth and capacity will be even slower than that of processor throughput. For this purpose, we suppose system architecture with memory hierarchy including hybrid memory devices, including non-volatile RAM (NVRAM), and develop new software technology that efficiently utilizes the hybrid memory hierarchy. The area of our research includes new compiler technology, memory management and application algorithms.
