TeraGrid Platform Challenge AIX 5.{1,2,3} on Power{3,4,5} Solaris 9 on UltraSparc IV Tru64 on Alpha EV{68,7} SGI ProPack 4 on IA-64 SLES 9 on PPC64 IBM BlueGene SUSE 9 on Opteron Cray XT3 SLES8 on IA-64 6 distributions on Linux on IA-32

Software Deployment Options Site/Resource Selected –Operating System or Distribution (local) –Scheduler and resource manager (network, possibly local) –Monitoring system (local, possibly network) –Vendor compiler, vendor MPI (network) CTSS - Common TeraGrid Software Stack –Administrator installed –Network file-system (TG_APPS_PREFIX) Personal Software –User installed –Network file-system (HOME) Community Software –Group installed –Network file-system (TG_COMMUNITY)

Requesting a CSA Web request form –Community name –Space requirement –Owner & maintainers –Which TeraGrid resources Request processing –Request distributed to sites –Tracked in TG ticket system

CSA Usage Network shared directory –Owner, community specific group –Group write permissions –Group controls world access to software Universal path - $TG_COMMUNITY/ /… Restrictions –No privileged access –No permanent services

Directions TeraGrid wide shared CSA –Wide-area GPFS More TeraGrid communities –Open Science Grid (OSG) –Gateways Software environment support Useful for multi-grid interoperability –PRAGMA and other Grids can deploy their software on the TeraGrid
