This is probably a little weird:

Through proper programming and hardware architecture design, would it be possible to create an array of Opteron processors in such a way that they could emulate the SIMD-based Cray machines in order to run the programs and instruction sets that are deemed as "Cray proprietary" solely because of the vector processors they use in some of their systems?
 
with a good understanding of what your trying to simulate, of course. all you need to do is bascially write emulation software, and figure out how to synch up work on multiple machines, ala clustering.

easy in theory, very difficult in practice.
design and write cray emulation software (vmware)
figure out how to spread the work out over multiple machines
 
Do you think there would be many hangups, though, in attempting to recompile the software that was supposed to be running on these totally different processors?....or perhaps the emulation could be good enough in order to fool the software to think it is running in its native environment?
