2. Outline Who and what is TIGRE? TIGRE Activities TIGRE Application Example Final Thoughts

3. Texas A&M Houston Texas Tech Univ. of Texas at Austin Who Is TIGRE? A project of the High Performance Computing Across Texas (HiPCAT) organization Composed of 5 leading research universities

4. What is TIGRE? Part of the State of Texas’ plan to support CyberInfrastructure —LEARN: $7.3M / 33 institutions –Lonestar Education And Research Network –Network (fiber, routers, etc.) to connect institutions  (But that’s another talk…) —TIGRE: $2.5M / 5 schools –People to build and support the software TIGRE goals —Implement and deploy grid software –Note: funded as construction project, not research —Support three applications “of economic interest to the State of Texas” —Document best practices, train potential users

12. T = 0T > 0 T =  Inverse Problem! UltraScan - A TIGRE Target Application Comprehensive data analysis package —Integrated data editing, analysis environment, MySQL database, parallel Monte Carlo analysis —From UT Health Science Center San Antonio For analytical ultracentrifugation experiments —Analyze wavelengths of scatted light –Many samples at many locations over time —Compute number of components, molecular weights, shapes, interactions —Solve by genetic algorithm (optimization) –Embarrassingly parallel, but overwhelms UTHSCSA’s 128-node cluster

16. Leveraging TIGRE for VGrADS Obvious target of opportunity —Two common players —Both sides reasonably open to collaboration —Both sides interested in outreach (albeit not the same kind) Application challenges —VGrADS contribution needs to be robust –Or modular and applied sparingly –2-phase scheduling, BQP may fit the bill now —New twists for VGrADS –DSNMO - needs dynamic compilation, may need app mgr –MCNP - needs access control –WRF-Chem - needs data management, may need deadline scheduling

20. Why TIGRE? (Do We Need Yet Another Grid?) Texas is looking to the future —Creating statewide CyberInfrastructure —Supporting existing research and education —Attracting new industry –TIGRE funded from Texas Enterprise Fund Computers and networks are already (partly) there —LEARN —UT Austin a partner in TeraGrid We need the people to make it work —Build the grid! –Funded as a construction project, not research —Support software —Reach out –To non-research schools, maybe to K-12
