Towards a Petascale Research Grid Infrastructure

Abstract

Grid computing will not only allow researchers to tackle large problems not possible with current computing infrastructures, but also will make available large, collaborative virtual computing environments throughout within organizations as well as across organizations, in some cases on a global scale. The talk will cover our ongoing R&D efforts to effectively implement such infrastructures that surmount to facilitating multi-teraflops to petaflops of computing power and multi-petabytes of storage in an ubiquitous fashion, namely (1) The Titech Campus Grid project, an experimental Grid deployment project within the Titech campus, consisting of over 1000 processors of various GSIC resources, (2) The KEK-AIST-KEK Gfarm project that is developing a middleware and a testbed to allow petascale processing of large-volume instrumentation data ranging up to over petabytes of storage requirements, and (3) the latest Japanese National Research Grid Initiative (NAREGI) that aims to build the next generation Grid middleware intended to be used throughout the research Grids in Japan as well as other in other countries, and structured to be a triage of Grid middleware R&D, Grid enabling of Nanoscience Applications, as well as facilitating of 100Teraflops scale testbed and demonstration of grand-challenge Nanoscince applications thereof.
