Uniform Driver Interface -- Public Source Code for runtime environments and drivers based on the UDI Specifications. Single source image for a driver, built once for each ABI (IA32, Sparc, etc.) and then run on any OS that provides UDI!
The project focuses on developing an environment where one can harness idle CPU cycles of numerous networked systems to work together on a particularly processing-intensive problem. (distributed computing you may call it)
