2. Project history The RENKEI project led by Prof. Ken Miura of NII is funded by MEXT during JFY2008-2011 The goal of the project was developing middleware for enabling e-Science KEK is a part of RENKEI and worked for developing a middle layer to absorb the differences among middleware including GRID, Cloud, batch queuing system and etc for application developers

3. Achievements Joined the SAGA working group – Developed the adaptors for the C++ implementation UGI has been developed as the python library – Web interface can be implemented easily by Django Applications are implemented using UGI – Particle therapy simulation and ILC

9. UGI Job Handling UGI job handling provides common mechanism to control job submission for different middleware. Each job submission script is written in the SAGA API. SAGA (C++) Adaptors developed by KEK – NAREGI, PBS-Pro, Torque Additional Interface Developed: – gLite-WMS–job ( gLite-CREAM-job adaptor is under development for SAGA C++ ) – Bulk job submission for NAREGI and gLite (Python wrapper for client commands) UGI Commands and API :Example ugi-job-submit ugi.job.submit(tasks) Steps to submit jobs – Create task object: ugi.job.task() Set path to the task script file: written with SAGA Select site to be run Select run mode: multiple sub./bulk sub. Set no. of jobs to be submitted to the site – Make a collection of task: tasks – Submit these tasks by ugi.job.submit(tasks) task is defined as a collection of jobs for a specific site. class task (); script site mode njobs 2010/10/279OGF30

11. UGI File Handling For seamless file management and access, SAGA file adaptors are used, and RNS (OGF Resource Namespace Service) is used for middleware independent file catalog. Broad range of file system middleware should be supported in the UGI for practical needs, such as gsiftp, LFC/SRM, Gfarm, iRODS, as well as UNIX local file system. SAGA Adaptors of Gfarm and iRODS are developed by KEK. Functionalities out side of SAGA are implemented by Python wrapper of client commands. Commands and API Example: ugi-file-ls ugi.file.ls() command path options(-l,…) ugi-file-ls /kek/ilc/mc-2008 : catalog path in RNS gsiftp://gftpserver.host/storage/exp1/ : files in gsiftp server lfn.//lfc-hostname/grid/... :files in gLite file://localhost/home/user01/data01/ :local file - - - - - - 2010/10/2711 OGF30

12. File catalog with RNS File Catalog is implemented using the RNS – RNS namespace is used for logical file catalog and keeps a file URL in the EPR – RNS accepts user-defined metadata for each file in the XML format. It is useful for data file search. – A local RNS catalog is possible to be adapted to the central RNS catalog seamlessly in a single tree structure,which is useful for not only load sharing but also for flexible catalog management. central/1ocal-1/…/local-2/kek/exp0101 OGF3012 Central RNS server local-1 local-2 local-3 2010/10/27

14. UGI Monitoring Monitoring might cover various monitoring of jobs, resources as well as application status based on a lightweight database. Current implementation is for job monitoring only. The job monitoring is possible to include not only job status but also job management information, input parameters of each job, input/output file information by key-value pairs. Each running job can update monitor database by XML-RPC server/client mechanism between UGI/SAGA host and each compute node. UGI/SAGA host Grid Database(sqlite3) 2010/10/2714OGF30 Compute nodes
