Killer App Challenge

An Industry Constantly Search for Killer AppsThe Killer App for X

What are the Killer Apps for Many-core?

Who needs 100 cores to run M/S Word?

What are the Killer Apps for Cloud?

We think everyone on the planet deserves to

have their own virtual data center in the cloud- Lew Tucker, CTO of SUN cloud group.

Note: During test, a 3D PC game was played using modified VNC client with the game running in Xen virtual guest on a remote Xen host, and gamevideo was streamed using H264. Desktop display of client was captured using capturemydesktop and converted to wmv for PPT embedding usingmencoder.
