NAREGI at KEK and GRID plans Takashi Sasaki KEK Computing Research Center

NAREGI status Beta-2 was released in October Packaged by rpm GRID interoperability package based on GIN is included We have completed the set up of the environment recently We are going to start the test soon

Future of NAREGI NAREGI version 1 will be released in the Spring of 2008 NAREGI will be a sub project of the 10 peta flops computer project http://www.nsc.riken.jp/index-eng.html They expect the budget cut, anyway Future plan is not clear still NII will operate NAREGI GOC as a part of their CSI

GRID interoperability GIN realized file transfer, mutual job submission and information exchange File catalogue is the issue still We have started to work with Osami Tatebe of Tsukuba University

Resource Namespace Service Specification Standardized in OGF http://www.ogf.org/documents/GFD.101.pdf Middleware independent No globus is required Two implementations are going on U. of Tsukuba http://www.ogf.org/OGF21/materials/957/OGF21%20RNS.pdf University of Virginia

RNS

Key issues How to synchronize with local file catalogues, such as, LFC? NAREGI has no built-in file catalogue and RNS will be their local catalogue, too Performance and robustness should be tested well

J-PARC New facility will be commissioned in 2008 Peta-bytes of data a year are expected HENP, material and biochemical science

KEK and J-PARC 60km Tokai Tsukuba Narita Airport J-PARC B-Factory Photon-Factory LC-Test Facility Tsukuba Narita Airport

J-PARC computing Data acquisition will be don at Tokai Only temporally storage Data will be sent to KEK and stored Network bandwidth How to automate ? How to distribute outside? SRB/iRODs LCG/NAREGI

Things to be explored Integration of the KEKB computer system with GRID According to the users preference Mass storage HPPS or something else? Virtual machine VMware or XEN? Load balancing File transfer between Tokai and Tsukuba

Future direction gLite and NAREGI will be operated at the same time Still worker nodes should be shared Virtual machine will be used SRB/iRODs would be a solution for smaller groups The same file space should be shared among local, SRB/iRODs, gLite and NAREGI

Plan NAREGI File catalogue System replacement More tests on beta-2 GRID interoperability File catalogue Collaboration with U. of Tsukuba System replacement Jan. 2009 Central computer system GRID based system 2012 Central computer system also KEKB system Unification of the systems to be considered

Application support should be provided Not only HENP, but material and biochemical/life science Hadron therapy simulation University support will be continued and extended if funded Nagoya, Kobe, Tohoku, Tsukuba and Hiroshima-IT are getting our support They have the complete LCG installation Remote installation and support Find a new budget resource to hire new people
