Finding 7) Testbeds

7)One needs hardware systems which can be used by system software developers to support software prototyping using emulation and simulation of proposed petacomputers. This will evaluate scaling of the software and reduce risk
- These systems must be available early so that working software is delivered at same time as deployed hardware
- This prototyping machine must allow one to change all parts of the operating system and so hard to share machine during prototyping
