a raspberry pi that plugs into a pci slot like a video card that assist your cpu or that you could send it task to complete so it dosent slow down your main cpu kinda of like with multicpu supercomputers

don't really think that a bus on the pi would be fast enough to do this. Also you wouldn't get a whole l of performance boosts out of this considering the pi runs @ 700 Mhz

50 years ago Seymour Cray designed the CDC 6600 which did something similar - a fast (for it's day!) CPU with 10 smaller, tightly coupled processors handling I/O, job scheduling and other O/S tasks, etc. in order to free up the CPU for user jobs. The 6600 was considered the first "super computer" (and interestingly, also the first RISC processor)

you can do this over a network. go look up the MPI protocols
Good luck!
