Issues of Global Computing systems
Communication Performance (throughput, latency)
- High latency ? deterrent to performance?
Computing Server Selection
- Criteria to select servers?
- Can supercomputers/MPPs be effectively shared by multiple remote clients? (Scheduling characteristics)
Sharing by Multiple clients
- Global computing servers on supercomputer/MPP OSes effectively handle multiple parallel tasks?
Remote Library Design and Reuse
- Allocate processors in a task-parallel / data-parallel manner ?
- The right “remote library” design, decomposition, API, etc.
