4. July 8, 2004Jae Yu, THEGrid Workshop Introduction 4 Why are we here? To mark the new beginning of a Texas alliance High Performance Computing Across Texas (HiPCAT, http://www.hipcat.net/http://www.hipcat.net/) organization is a consortium of many universities in Texas to collaborate in bringing high level computing to the community spanning wide ranges –Education –Research –Industry

5. July 8, 2004Jae Yu, THEGrid Workshop Introduction 5 Why are we here, cont’d High Energy Physics anticipates large amount of data (over several Peta Bytes – million GB, 10000, 100GB drives) to be shared throughout the world –Provide excellent problems to solve through cutting edge technology Construct a nucleus grid that must solve immediate problems Bring computing grid technology one step closer to every day lives to improve quality of life Need to promote grass root effort in Texas

6. July 8, 2004Jae Yu, THEGrid Workshop Introduction 6 High Energy Physics in Texas Several Universities –UTA, TTU, SMU, UTD, TAM, UH, UT, Rice, UTB, UTEP, etc UTA and TTU play leading role in their Tevatron experiments Many different research facilities used –Fermi National Accelerator Laboratory –Jefferson Lab –Brookhaven National Lab –CERN, Switzerland, DESY, Germany, and KEK, Japan –SLAC, CA and Cornell –Natural sources and underground labs Sizable community, variety of experiments and needs Large data (~1PB/experiment) now!!

12. July 8, 2004Jae Yu, THEGrid Workshop Introduction 12 Where are we and where do we want to go? Grid solutions are being implemented and used Discover additional computing resources Accumulate local expertise to help each other Data analysis at remote universities being done Operational grid producing MC samples Time to work with each other within Texas to maximally utilize the ample resources Help expediting realization of computing grid

13. July 8, 2004Jae Yu, THEGrid Workshop Introduction 13 Workshop Goals Primary goals: –Kick-start Texas High Energy Grid, THEGrid –Prepare THEGrid sites for the "grid" environment (Globus, Condor, etc.) via hands-on sessions –Understand the software & hardware requirements –Set clear goals and their corresponding time scales for eventual integration of THEGrid into the global grid activities, such as Grid3 and Open Science Grid –Decide on work assignments for participating institutions –Identify available resources within the field in the state of Texas –Set common goals, task lists and schedules Distribute tasks Establish clear road map and milestones for the future
