SURA Regional HPC Grid Proposal Ed Seidel LSU With Barbara Kucera, Sara Graves, Henry Neeman, Otis Brown, others

Basic Plan Strengthen SURAgrid to create the leading regional HPC environment –Deploy numerous supercomputers across region –Leverage regional investments in optical networks SURA, NLR, RONs 1 Gbit to many sites makes regional, national integration possible as never before –Coordinate deployment, operations Major impact across region

Operational Plan Tight integration of HPC systems –Globally shared file system –Common base software stack –Metascheduling Machines respond both to local and regional needs –Majority of cycles locally controlled –Some fraction available for the regional use, coordinated training, preparation for codes to run at national centers

Primary Advantages HPC Resource Sharing, load balancing Regional (SURA sponsored), national training Compatibility with national HPC centers –SURA underrepresented by –Existing (NCSA, SDSC, NERSC, TACC, etc) –Future: LSU proposal, many others Specific Projects –SCOOP, LEAD, Dynacode –Event-driven computing –Other projects much easier to develop with regional HPC support IBM partnership

Software Deployment Open Source –linux –Globus, Condor, Cactus, SAGA, MPICH, etc –Eclipse –Spruce, TeraGrid CTSS IBM –AIX –GPFS-WAN –HPC Cluster software –ESSL

IBM Partnership Hardware –Power5, Power6: very responsive Software –Metascheduling, load balancing, migration of LPARS, MPI jobs –Development environment Eclipse, Cactus, ESSL, Portals Usage scenarios –Event-driven, DDDAS Other HPC systems, software welcome and encouraged –TeraGrid model applies: all vendors connected

Financials Very unusual value for major vendor –Price down to commodity levels –$1.2M system for $350K, including 3 years of maintenance (at roughly $112K) SURA contribution likely if strong regional support is seen –Both hardware and personnel support possible Some sites willing to help administer –LSU, others

Participating Groups Expecting to participate: Kentucky, LSU, Oklahoma, UAH, Miami Considering participation: TAMU, Houston, TACC, RENCI Others
