How?

Be unreasonable

The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.

• A group of rendering nodes generate pixel data for an application

• SAGE captures the pixel data streams over tiled display

• Free Space Manager controls pixel streams

IssuesIssues• Precedent

– Little or none• 10G Networking

– Production networks not feasible• 1080i HDTV uncompressed ~ 1.5 Gb / second• HP 8400 config

– HD SDI cards– Strange HP NIC Ops

• Windows XP– Configuration– Security

• Vendor/System Integrator familiarity– Typical classroom hardware may not work– HD best practices

• Standards– SMPTE, AES
