• Multiple physical experiments– At different geographic sites– Resources owned by different organizations– Heterogeneous control platforms
• Multiple computational simulations– At different geographic sites– Resources owned by different organizations– Heterogeneous simulation platforms– Sometimes used in place of physical
experiments are a “real” grid application.• NTCP works:
– Earthquake engineers are developing and using their own clients and plugins.
– Its failure-recovery features have allowed experiments to continue after transient network failures
• But there’s still work to do…– NTCP requires some shared knowledge between developers
of clients and plugins. Better use of service data could fix this.
– Some aspects of the protocol need to be “cleaned up”– There’s not much support for recovering from backend
failures.
